What is (are) Skin Cancer ? | Skin cancer is the most common type of cancer in the U.S. It occurs in more than a million people each year, including many older people. There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma. Of the three, melanoma is the most serious. The Body's Largest Organ The skin is the body's largest organ. It has two main layers: the inner layer, called the dermis, and the outer layer, called the epidermis. The dermis contains sweat glands, nerves, hair follicles, and blood vessels. The epidermis forms the protective, waterproof layer of the skin. The very top of the epidermis, which is called the stratum corneum, is made up of dead cells that have moved their way up through the other layers. The epidermis, or outer layer, is made up of three types of living cells: - Squamous cells are flat and form the top layer of living cells. - Basal cells are round and lie directly under squamous cells. - Melanocytes are specialized skin cells that produce pigment called melanin. Squamous cells are flat and form the top layer of living cells. Basal cells are round and lie directly under squamous cells. Melanocytes are specialized skin cells that produce pigment called melanin. The melanin pigment produced by melanocytes gives skin its color. It also protects the skin from ultraviolet (UV) ray damage from the sun by absorbing and scattering the energy. People with more melanin have darker skin and better protection from UV light. People with lighter skin (less melanin) are more vulnerable to damage from UV light. How Tumors Form Normally, cells in the body grow, divide, and produce more cells as needed. But sometimes the process goes wrong -- cells become abnormal and multiply in an uncontrolled way. These extra cells form a mass of tissue, called a growth or tumor. Tumors can be relatively harmless (benign) or cancerous (malignant). A malignant tumor can spread, damage healthy tissue, and make a person ill. Skin cancer occurs when abnormal cells form and multiply in an uncontrolled way in the epidermis, or abnormal cells from the epidermis invade the dermis of the skin. Basal cell carcinoma, squamous cell carcinoma, and melanoma are skin cancers that are named for the epidermal cells from which they develop. Basal Cell and Squamous Cell Carcinoma Basal cell and squamous cell carcinomas are very common in both older and younger people and are rarely life-threatening. Melanoma is a less common, yet more serious, type of skin cancer. Basal cell and squamous cell carcinomas are often called non-melanoma skin cancers or keratinocyte cancers. Melanoma Melanoma results from the uncontrolled growth of melanocytes and can occur anywhere on the body where melanocytes are located, including the skin, eyes, mouth and gastrointestinal tract. Men tend to develop melanoma more often on the trunk (the area from the shoulders to the hips) or the head and neck. Women more often develop melanoma on the extremities (arms and legs). Melanoma is found most often in adults, but can occur in children and teenagers. Melanoma is the most serious and most aggressive (fastest growing) form of skin cancer. An estimated 76,690 new cases of melanoma will be diagnosed in 2013. Because it is difficult to adequately treat melanoma after it has spread, the disease is expected to claim the lives of approximately 9,480 Americans in 2013. Can Skin Cancer Be Treated? Most basal cell and squamous cell skin cancers can be cured if found and treated early. Melanoma can often be treated effectively if caught in time. |

What causes Skin Cancer ? | Scientists have been able to identify the causes and risk factors for skin cancer. A risk factor is anything that increases your chances of getting a disease. DNA Damage One of the main reasons that skin cancer develops is because DNA is damaged. DNA is the master molecule that controls and directs every cell in the body. Damage to DNA is one of the ways that cells lose control of growth and become cancerous. DNA mutations can also be inherited. Exposure to Ultraviolet Radiation Excess exposure to ultraviolet (UV) light can damage the DNA in skin cells and increase a person's risk for both melanoma and non-melanoma skin cancer. UV light is invisible radiation from the sun that can damage DNA. Skin cells are especially susceptible to DNA damage since they are frequently exposed to UV light. There are three types of UV radiation: A, B, and C. All three are dangerous and able to penetrate skin cells. UVA is the most common on earth, and is harmful to the skin. UVB is less common because some of it is absorbed by the ozone layer. It is less harmful than UVA, but can still cause damage. UVC is the least dangerous because although it can cause the most damage to the skin, almost all of the UVC rays are absorbed by the ozone layer. Sources of Ultraviolet Radiation UV radiation comes from the sun, sunlamps, tanning beds, or tanning booths. UV radiation is present even in cold weather or on a cloudy day. A person's risk of skin cancer is related to lifetime exposure to UV radiation. Most skin cancer appears after age 50, but the sun damages the skin from an early age. The body has systems to repair DNA and control some mutations, but not all of them. The risk of cancer increases as we age because sometimes cancer is caused by many mutations accumulating over time. Role of the Immune System The body's immune system is also responsible for recognizing and killing abnormal cells before they become cancerous. As we get older, our immune systems are less able to fight infection and control cell growth. People whose immune system is weakened by certain other cancers, medications, or by HIV are at an increased risk of developing skin cancer. Basal Cell and Squamous Cell Carcinoma Besides risk factors that increase a person's chance of getting any type of skin cancer, there are risk factors that are specific to basal cell carcinoma and squamous cell carcinoma, the non-melanoma skin cancers. These risk factors include - scars or burns on the skin - chronic skin inflammation or skin ulcers - infection with certain human papilloma viruses - exposure to arsenic at work - radiation therapy - diseases that make the skin sensitive to the sun, such as xeroderma pigmentosum, albinism, and basal cell nevus syndrome - medical conditions or drugs that suppress the immune system - personal history of one or more skin cancers - family history of skin cancer - certain diseases of the skin, including actinic keratosis and Bowen's disease. scars or burns on the skin chronic skin inflammation or skin ulcers infection with certain human papilloma viruses exposure to arsenic at work radiation therapy diseases that make the skin sensitive to the sun, such as xeroderma pigmentosum, albinism, and basal cell nevus syndrome medical conditions or drugs that suppress the immune system personal history of one or more skin cancers family history of skin cancer certain diseases of the skin, including actinic keratosis and Bowen's disease. Someone who has one or more of these risk factors has a greater chance of getting skin cancer than someone who does not have these risk factors. However, having these risk factors does not guarantee a person will get skin cancer. Many genetic and environmental factors play a role in causing cancer. Melanoma Melanoma is less common than non-melanoma skin cancers like basal cell carcinoma and squamous cell carcinoma, but it is more serious. The factors that increase a person's chance of getting melanoma are - severe, blistering sunburns earlier in life - unusual moles (normally benign clusters of melanocytes) - large quantity of ordinary moles (more than 50) - white or light-colored (fair) skin, especially with freckles. - blond or red hair - blue or green eyes - being older than 20 years of age. severe, blistering sunburns earlier in life unusual moles (normally benign clusters of melanocytes) large quantity of ordinary moles (more than 50) white or light-colored (fair) skin, especially with freckles. blond or red hair blue or green eyes being older than 20 years of age.

However, having these risk factors does not guarantee a person will get cancer. Many genetic and environmental factors play a role in causing cancer. Reducing Your Risk While exposure to UV radiation is a major risk factor for cancer, skin cancer can occur anywhere on the skin, not just in sun-exposed areas. The best ways to reduce your risk of skin cancer are to - avoid outdoor activities during midday, when the sun's rays are strongest - wear protective clothing such as a wide-brimmed hat, long-sleeved shirt, and pants. avoid outdoor activities during midday, when the sun's rays are strongest wear protective clothing such as a wide-brimmed hat, long-sleeved shirt, and pants. Darker-colored clothing is more protective against the sun. For example, a white t-shirt, particularly if it gets wet, provides little resistance to UV rays. In addition, wearing sunglasses that wrap around the face or have large frames is a good way to shield the delicate skin around the eyes. Wear Sunscreen and Lipscreen When exposed to sunlight, you should always wear sunscreen and lipscreen. If possible, choose sunscreen and lipscreen labeled "broad-spectrum" (to protect against UVA and UVB rays). Your sunscreen should have an SPF, or sun protection rating, of at least 15. The SPF of a sunscreen is a measure of the time it takes to produce a sunburn in a person wearing sunscreen compared to the time it takes to produce a sunburn in a person not wearing sunscreen. This varies from person to person, so be sure to reapply sunscreen every 2-3 hours. |

What are the symptoms of Skin Cancer ? | Early Detection is Important When skin cancer is found early, it is more likely to be treated successfully. Therefore, it is important to know how to recognize the signs of skin cancer in order to improve the chances of early diagnosis. Most non-melanoma skin cancers (basal cell carcinoma and squamous cell carcinoma) can be cured if found and treated early. Skin Changes A change on the skin is the most common sign of skin cancer. This may be a new growth, a sore that doesn't heal, or a change in an old growth. Not all skin cancers look the same. Sometimes skin cancer is painful, but usually it is not. Checking your skin for new growths or other changes is a good idea. Keep in mind that changes are not a sure sign of skin cancer. Still, you should report any changes to your health care provider right away. You may need to see a dermatologist, a doctor who has special training in the diagnosis and treatment of skin problems. A Mole That is Bleeding Also see a doctor if a mole is bleeding or if more moles appear around the first one. Most of the time, these signs are not cancer. Sometimes, it is not even a mole. Still, it is important to check with a doctor so that any problems can be diagnosed and treated as early as possible. Don't ignore your symptoms because you think they are not important or because you believe they are normal for your age. Signs of Melanoma Melanoma skin cancer is more difficult to treat, so it is important to check for signs and seek treatment as soon as possible. Use the following ABCDE rule to remember the symptoms of melanoma. See a doctor if you have a mole, birthmark, or other pigmented area of skin with A = Asymmetry. One half of the mole looks different than the other half. (top left image) B = Border. The edges are often ragged, notched, or blurred in outline. The pigment may spread into the surrounding skin. (top right image) C = Color. The mole is more than one color. Shades of black, brown, and tan may be present. Areas of white, gray, red, pink, or blue may also be seen.(bottom left image) D = Diameter.There is a change in size, usually an increase. Melanomas can be tiny, but most are larger than the size of a pea (larger than 6 millimeters or about 1/4 inch). (bottom right image) E = Evolving. The mole has changed over the past few weeks or months. |

How to diagnose Skin Cancer ? | What Happens During Screening? Checking for cancer in a person who does not have any symptoms is called screening. Screening can help diagnose skin problems before they have a chance to become cancerous. A doctor, usually a dermatologist, screens for skin cancer by performing a total-body skin examination. During a skin exam, the dermatologist or other health care professional looks for changes in the skin that could be skin cancer, and checks moles, birth marks, or pigmentation for the ABCD signs of melanoma. He or she is looking for abnormal size, color, shape, or texture of moles, and irregular patches of skin. Screening examinations are very likely to detect large numbers of benign skin conditions, which are very common in older people. Even experienced doctors have difficulty distinguishing between benign skin irregularities and early carcinomas or melanomas. To reduce the possibility of misdiagnosis, you might want to get a second opinion from another health professional. Self-Examinations You can also perform self-examinations to check for early signs of melanoma. Make sure to have someone else check your back and other hard to see areas. Do not attempt to shave off or cauterize (destroy with heat) any suspicious areas of skin. Risk Tool The National Cancer Institute developed a Melanoma Risk Tool which can help patients and their doctors determine their risk. The tool can be found at http://www.cancer.gov/melanomarisktool/. Performing a Biopsy In order to diagnose whether or not there is skin cancer, a mole or small piece of abnormal skin is usually removed. Then, a doctor will study the suspicious cells under a microscope or perform other tests on the skin sample. This procedure is called a biopsy. It is the only sure way to diagnose skin cancer. You may have the biopsy in a doctor's office or as an outpatient in a clinic or hospital. Where it is done depends on the size and place of the abnormal area on your skin. You may have local anesthesia, which means that you can be awake for the procedure. If Cancer Is Found If the biopsy shows you have cancer, tests might be done to find out if cancer cells have spread within the skin or to other parts of the body. Often the cancer cells spread to nearby tissues and then to the lymph nodes. Has the Cancer Spread? Lymph nodes are an important part of the body's immune system. Lymph nodes are masses of lymphatic tissue surrounded by connective tissue. Lymph nodes play a role in immune defense by filtering lymphatic fluid and storing white blood cells. Often in the case of melanomas, a surgeon performs a lymph node test by injecting either a radioactive substance or a blue dye (or both) near the skin tumor. Next, the surgeon uses a scanner to find the lymph nodes containing the radioactive substance or stained with the dye. The surgeon might then remove the nodes to check for the presence of cancer cells. If the doctor suspects that the tumor may have spread, the doctor might also use computed axial tomography (CAT scan or CT scan), or magnetic resonance imaging (MRI) to try to locate tumors in other parts of the body. |

What are the treatments for Skin Cancer ? | Many Treatment Options There are many treatment options for people with melanoma and non-melanoma skin cancer. The choice of treatment depends on your age and general health, the site of the cancer, the stage of the cancer, whether or not it has spread beyond the original site, and other factors. If tests show that you have cancer, you should talk with your doctor and make treatment decisions as soon as possible. Studies show that early treatment leads to better chances for successful outcomes. In some cases, all of the cancer is removed during the biopsy, and no further treatment is needed. For others, more treatment will be needed, and a doctor can explain all of the treatment options. Working With a Team of Specialists A person with skin cancer, particularly if it is melanoma, is often treated by a team of specialists. The team will keep the primary doctor informed about the patient's progress. The team may include a medical oncologist (a specialist in cancer treatment), a dermatologist (a specialist in skin problems), a surgeon, a radiation oncologist (a specialist in radiation therapy), and others. Before starting treatment, you may want another doctor to review the diagnosis and treatment plan. Some insurance companies require a second opinion. Others may pay for a second opinion if you request it. Plan Ahead for Doctor Visits When planning your skin cancer treatment, you may meet with many different health care providers, get lots of information, and have lots of questions. Plan ahead for doctor appointments by writing down your questions and bringing a paper and pen to take notes. Sometimes it also helps to bring a friend or family member to your doctor appointments so they can help you listen, take notes, ask questions, and give you support. Clinical Trials for Skin Cancer Some skin cancer patients take part in studies of new treatments. These studies, called clinical trials, are designed to find out whether a new treatment is safe, effective, and better than the current standard of care. Often, clinical trials compare a new treatment with a standard one so that doctors can learn which is more effective. Talk to your doctor if you are interested in taking part in a clinical trial. The U.S. National Institutes of Health, through its National Library of Medicine and other Institutes, maintains a database of clinical trials at ClinicalTrials.gov. - Click here to see a list of the current clinical trials on melanoma. - Click here to see a list of the current clinical trials on non-melanoma skin cancer.

what research (or clinical trials) is being done for Skin Cancer ? | Many Areas of Research Scientists are constantly searching for new ways to detect skin cancer, assess risk, and predict patient outcomes. They are interested in finding new treatments and new ways to deliver drugs and radiation. As scientists get a better understanding of what causes skin cancer and what genetic and environmental factors play a role, they should be able to design new drugs to hinder the development of cancer. Clinical trials are designed to answer important questions and to find out whether new approaches are safe and effective. Research has already led to advances, such as photodynamic therapy, and researchers continue to search for better ways to prevent and treat skin cancer. Researching Techniques to Deliver Drugs One area that scientists are working on is development of techniques for delivering chemotherapy drugs directly to the area around the tumor, rather than sending the chemotherapy through the entire body. One of these techniques is called hyperthermic isolated limb perfusion. Hyperthermic isolated limb perfusion sends a warm solution containing anti-cancer drugs directly to the arm or leg in which the cancer is located. A tourniquet is used to temporarily cut off the blood flow while the chemotherapy drugs are injected directly into the limb. This allows the patient to receive a high dose of drugs only in the area where the cancer occurred. Genetic Research For basal cell carcinoma and squamous cell carcinoma, researchers are studying gene changes that may be risk factors for the disease. They also are comparing combinations of biological therapy and surgery to treat basal cell cancer. Discovering links between inherited genes, environmental factors, and skin cancer is another area of research that might provide scientists with insight they can use to screen people to determine their risk for the disease. Recently, scientists at the National Cancer Institute (NCI) found one genetic link that dramatically increases the chance of developing melanoma. Research on Melanoma Treatments Other studies are currently exploring new treatment options for melanoma. One recent study discovered a protein that may help block the development and spread of melanoma. This discovery could lead to a new treatment for melanoma patients in the future. Several other studies are examining the potential for using vaccines to treat melanoma. An Advance in Treating Melanoma In June of 2011, an important advance in treating melanoma was announced at an annual cancer meeting. A drug called ipilimumab was approved for treating the disease, and it works differently than traditional chemotherapy. It uses immunotherapy to help the immune system recognize and reject cancer cells. When its successful, immunotherapy can lead to complete reversal of even advanced disease. Some patients with stage IV metastatic disease who were treated in early immunotherapy trials after other therapies were unsuccessful are still in complete remission more than 20 years later. Vaccine Research Traditional vaccines are designed to prevent diseases in healthy people by teaching the body to recognize and attack a virus or bacteria it may encounter in the future. Cancer vaccines, however, are given to people who already have cancer. These vaccines stimulate the immune system to fight against cancer by stopping its growth, shrinking a tumor, or killing the cancer cells that were not killed by other forms of treatment. Developing a vaccine against a tumor such as melanoma is more complicated than developing a vaccine to fight a virus. Clinical trials are in progress at the National Cancer Institute and other institutions to test the effectiveness of treating stage III or stage IV melanoma patients with vaccines. |

What is (are) Skin Cancer ? | The body is made up of many types of cells. Normally, cells grow, divide, and produce more cells as needed to keep the body healthy. Sometimes, the process goes wrong. Cells become abnormal and form more cells in an uncontrolled way. These extra cells form a mass of tissue, called a growth or tumor. Tumors can be benign, which means not cancerous, or malignant, which means cancerous. |
|
What is (are) Skin Cancer ? | Skin cancer occurs when cancer cells form in the tissues of the skin. The skin is mainly made up of two layers: the inner layer, called the dermis, and the outer layer, called the epidermis. Within the epidermis, there are three types of cells; squamous cells, basal cells, and melanocytes. There are three types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma. The types of cancer are named after the type of cells that are affected. Basal cell carcinoma and squamous cell carcinoma are very common, especially in older people. However, they are rarely life-threatening. Melanoma is a less common, yet more serious, type of cancer. |
|
What is (are) Skin Cancer ? | Basal cell carcinoma develops in the basal cells of the epidermis, the outer layer of the skin. It is the most common type of skin cancer in the United States, but it spreads slowly and is rarely life-threatening. Basal cell carcinoma occurs most often on parts of the body that have been exposed to the sun, such as the face, ears, neck, hands and legs. However, it can be found on any part of the body. |
|
What is (are) Skin Cancer ? | Squamous cell carcinoma develops in the squamous cells of the epidermis, the outer layer of the skin. It is much less common than basal cell carcinoma and is rarely life-threatening. Squamous cell carcinoma occurs most often on parts of the body that have been exposed to the sun, such as the face, ears, neck, hands and legs. However, it can be found on any part of the body. |
|
What is (are) Skin Cancer ? | Melanoma is the fastest growing and most invasive type of skin cancer. This cancer arises from overgrowth of melanocytes. Melanocytes are specialized skin cells that produce a pigment called melanin. |
|
What is (are) Skin Cancer ? | When the cancer spreads from its original tumor location in the skin to another part of the body such as the brain, it is called metastatic skin cancer. It is not the same as a cancer that started in the brain (brain cancer). Doctors sometimes call this "distant" disease. |
|
Who is at risk for Skin Cancer? ? | Skin cancer is caused by DNA damage, which can result from excess exposure to ultraviolet (UV) light. Having a previous occurrence of skin cancer or a close family member with the disease also puts you at risk for skin cancer. Other risk factors include having - a weak immune system - unusual moles or a large number of moles - white or light (fair)-colored skin, especially with freckles - blond or red hair or blue or green eyes - scars or burns on the skin, or skin diseases that make someone sensitive to the sun. a weak immune system unusual moles or a large number of moles white or light (fair)-colored skin, especially with freckles blond or red hair or blue or green eyes scars or burns on the skin, or skin diseases that make someone sensitive to the sun.

Who is at risk for Skin Cancer? ? | The best way to reduce your skin cancer risk is to reduce your exposure to ultraviolet (UV) rays from the sun. To do this, you can avoid outdoor activities during midday, when the sun's rays are strongest, or wear protective clothing, such as a wide-brimmed hat, long-sleeved shirt, and pants. (Watch the video to learn more about how to protect your skin. To enlarge the video, click the brackets in the lower right-hand corner.

What are the symptoms of Skin Cancer ? | Skin cancer is usually visible. Changes in your skin, such as lumps, scabs, red spots, rough patches, or new or irregular moles should be reported to your doctor. You should also see a doctor if you have a mole, birthmark, or other pigmented area of skin that can be classified by the ABCDE symptom system. ABCDE stands for Melanoma skin cancer is more difficult to treat, so it is important to check for signs and seek treatment as soon as possible.

What is (are) Skin Cancer ? | Once cancer has been found, the doctor will need to determine the extent, or stage, of the cancer. Through staging, the doctor can tell if the cancer has spread and, if so, to what parts of the body. More tests may be performed to help determine the stage. Knowing the stage of the disease helps you and the doctor plan treatment. Staging will let the doctor know - the size of the tumor and exactly where it is - if the cancer has spread from the original tumor site - if cancer is present in nearby lymph nodes - if cancer is present in other parts of the body. the size of the tumor and exactly where it is if the cancer has spread from the original tumor site if cancer is present in nearby lymph nodes if cancer is present in other parts of the body. The choice of treatment is based on many factors, including the size of the tumor, its location in the layers of the skin, and whether it has spread to other parts of the body. For stage 0, I, II or III cancers, the main goals are to treat the cancer and reduce the risk of it returning. For stage IV cancer, the goal is to improve symptoms and prolong survival. |

What are the treatments for Skin Cancer ? | Different types of treatment are available for patients with skin cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. Four types of standard treatment are used: surgery, radiation therapy, chemotherapy, photodynamic therapy, and immunotherapy. Another therapy, biologic therapy, is one of many therapies currently being tested in clinical trials. These standard cancer treatments work in different ways. - Surgery removes the cancer. - Chemotherapy uses anti-cancer drugs to kill cancer cells or stop their growth. - Radiation therapy uses high-energy beams to kill cancer cells and shrink tumors. - Photodynamic therapy uses a drug and a type of laser light to kill cancer cells. - Immunotherapy, which is newer, uses the patient's own immune system to fight the cancer.

What are the treatments for Skin Cancer ? | Yes. Some skin cancer patients take part in studies of new treatments. These studies, called clinical trials, are designed to find out whether a new treatment is both safe and effective. Clinical trials are research studies with people to find out whether a new drug, therapy, or treatment is both safe and effective. New therapies are tested on people only after laboratory and animal studies show promising results. The Food and Drug Administration sets strict rules to make sure that people who agree to be in the studies are treated as safely as possible. Often, clinical trials compare a new treatment with a standard one so that doctors can learn which is more effective. Talk to your doctor if you are interested in taking part in a clinical trial.

How to prevent Prescription and Illicit Drug Abuse ? | Many Reasons for Abuse Drug abuse, whether prescription or illicit drugs, can have serious consequences, particularly for older adults. That is why prevention is key. However, there are many different reasons why people abuse drugs and become addicted to them. These reasons need to be taken into account when considering how to best prevent drug abuse. Family members, friends, pharmacists, and health care providers can all be involved in preventing drug abuse among older adults. Preventing Medication Abuse There are steps that you as a patient can take to prevent abuse of prescription medications and its consequences. - When visiting the doctor or pharmacist, bring along all prescription and over-the-counter medicines that you take -- or a list of the medicines and their dosages (how much you take and how often). Your doctor can make sure your medicines are right for you and make changes if necessary. - Always follow medication directions carefully. - Only use the medication for its prescribed purpose. - Do not crush or break pills. - If you are not sure how to take a medicine correctly, ask your doctor or pharmacist. He or she can tell you how to take a medication properly and about side effects to watch out for and interactions with other medications. - Ask how the medication will affect driving and other daily activities. - Do not use other people's prescription medications, and do not share yours. - Talk with your doctor before increasing or decreasing the medication dosage.

Preventing Illicit Drug Use Preventing illicit drug use in older adults requires first knowing what contributes to it. For people of all ages, an individuals biology (including their genetics) and the environment, as well as how the two act together, determine a persons vulnerability to drug abuse and addiction -- or can protect against it. For example, being exposed to drugs of abuse in youth, living in a community where drug use is prevalent, having untreated mental disorders, such as depression, or dealing with difficult transition periods such as retirement or loss of a spouse can all make an older adult more vulnerable to drug abuse. Prevention Requires Various Approaches Prevention efforts must focus on gaining a better understanding of the factors that promote illicit drug use in older adults. Prevention also includes finding ways to stop drug use before it worsens and leads to health problems, including addiction. Family members can play an important role by being aware of an older relatives well-being and possible drug abuse, and stepping in to help at an early stage, if necessary. Doctors should ask their older patients about potential drug abuse and make referrals as needed. |

What is (are) Prescription and Illicit Drug Abuse ? | Addiction is a chronic disease in which a person craves, seeks, and continues to abuse a legal (medication, alcohol, tobacco) or an illicit (illegal) drug, despite harmful consequences. People who are addicted continue to abuse the substance even though it can harm their physical or mental health, lead to accidents, or put others in danger. For more on drugs and the brain, see Drugs, Brains and Behavior: The Science of Addiction. |
|
What is (are) Prescription and Illicit Drug Abuse ? | Physical dependence is a normal process that can happen to anyone taking a medication for a long time. It means that the body (including the brain) is adapting to the presence of the drug, and the person may require a higher dosage or a different medication to get relief; this condition is known as tolerance. They may also suffer from withdrawal or feel sick when they stop taking the medication abruptly. However, the symptoms of withdrawal can usually be prevented or managed by a physician, which is why it is so important to talk to a doctor before stopping a medication. Someone who is addicted to a drug may also be physically dependent on it, but rather than benefitting from the drugs effects, an addicted person will continue to get worse with continued or increasing drug abuse. An addicted person compulsively seeks and abuses drugs, despite their negative consequences. |
|
What are the symptoms of Prescription and Illicit Drug Abuse ? | A persons behavior, especially changes in behavior, can signal a possible substance abuse problem. For example, you may notice that an older adult seems worried about whether a medicine is really working, or complains that a doctor refuses to write a prescription. He or she may have new problems doing everyday tasks or withdraw from family, friends, and normal activities. Other possible warning signs include - rapid increases in the amount of medication needed - frequent requests for refills of certain medicines - a person not seeming like themselves (showing a general lack of interest or being overly energetic) - "doctor shopping" -- moving from provider to provider in an effort to get several prescriptions for the same medication - use of more than one pharmacy - false or forged prescriptions. rapid increases in the amount of medication needed frequent requests for refills of certain medicines a person not seeming like themselves (showing a general lack of interest or being overly energetic) "doctor shopping" -- moving from provider to provider in an effort to get several prescriptions for the same medication use of more than one pharmacy false or forged prescriptions. |

What is (are) Prescription and Illicit Drug Abuse ? | The prescription medications most commonly abused by people of any age are opioids (painkillers), depressants, and stimulants. Doctors prescribe opioids to relieve pain and, sometimes, to treat severe coughs and diarrhea. Common opioid prescription medications include the following: - morphine (MS Contin, Kadian, Avinza), which is used before and after surgical procedures to treat severe pain - codeine (Tylenol with Codeine, Robitussin AC), which is prescribed for mild pain - hydrocodone (Vicodin, Lortab, Zydone), which is prescribed to relieve moderate to severe pain - oxycodone (OxyContin, Percodan, Percocet, Tylox, Roxicet), which is used to relieve moderate to severe pain - fentanyl (Duragesic), which is a strong pain medication typically delivered through a pain patch and prescribed for severe ongoing pain morphine (MS Contin, Kadian, Avinza), which is used before and after surgical procedures to treat severe pain codeine (Tylenol with Codeine, Robitussin AC), which is prescribed for mild pain hydrocodone (Vicodin, Lortab, Zydone), which is prescribed to relieve moderate to severe pain oxycodone (OxyContin, Percodan, Percocet, Tylox, Roxicet), which is used to relieve moderate to severe pain fentanyl (Duragesic), which is a strong pain medication typically delivered through a pain patch and prescribed for severe ongoing pain For more on opioids, see What Are the Possible Consequences of Opioid Use and Abuse?" Depressants are used to treat anxiety and sleep disorders. The types of depressants that are most commonly abused are barbiturates (Secobarbital ,Mebaral and Nembutal) and benzodiazepines (Valium, Librium, and Xanax). For more on depressants, see What Are the Possible Consequences of CNS Depressant Use and Abuse?" Stimulants are used to treat narcolepsy (a sleep disorder), attention deficit hyperactivity disorder (ADHD), and depression that has not responded to other treatments. These medications increase alertness, attention, and energy. Stimulants include methylphenidate (Ritalin and Concerta), and amphetamines (Adderall). For more on stimulants, see What Are the Possible Consequences of Stimulant Use and Abuse?" |
|
What causes Prescription and Illicit Drug Abuse ? | Medications affect older people differently than younger people because aging changes how the body and brain handle these substances. As we age, our bodies change and cannot break down and get rid of substances as easily as before. This means that even a small amount of a medicine or a drug can have a strong effect. If you take medications the wrong way or abuse illicit drugs, this can have a serious effect on your health and make existing health problems worse. As people age, they may also become more sensitive to alcohols effects. For more information on the dangers of mixing alcohol and medicines, see Alcohol Use and Older Adults." |
|
What is (are) Prescription and Illicit Drug Abuse ? | Marijuana is the most abused illicit drug among people 50 and older. |
|
What are the treatments for Prescription and Illicit Drug Abuse ? | Although under federal law, marijuana is illegal to use under any circumstance, in some states doctors are allowed to prescribe it for medical use. However, solid data on marijuanas health benefits is lacking, and for smoked marijuana many health experts have concerns about the potential negative effects on the lungs and respiratory system. The U.S. Food and Drug Administration has not approved smoked marijuana to treat any disease. They have approved two medications that are chemically similar to marijuana to treat wasting disease (extreme weight loss) in people with AIDS and to treat nausea and vomiting associated with cancer treatment. |
|
What are the symptoms of Prescription and Illicit Drug Abuse ? | Not always. Some warning signs, such as sleep problems, falls, mood swings, anxiety, depression, and memory problems -- can also be signs of other health conditions. As a result, doctors and family members often do not realize that an older person has a drug problem, and people may not get the help they need. |
|
What are the treatments for Prescription and Illicit Drug Abuse ? | Depending on the substance(s) involved, treatment may include medications, behavioral treatments, or a combination. A doctor, substance abuse counselor, or other health professional can determine the right treatment for an individual. Treatment helps people reduce the powerful effects of drugs on the body and brain. In doing so, treatment helps people improve their physical health and everyday functioning and regain control of their lives. Once in treatment, older adults do just as well or better than younger adults. |
|
What are the treatments for Prescription and Illicit Drug Abuse ? | People can receive treatment as outpatients (they live at home and visit the doctor or other provider) or through inpatient services (they live temporarily at a special facility where they get treatment). The support of family and friends is important during the treatment process. |
|
What are the treatments for Prescription and Illicit Drug Abuse ? | The first step in a substance treatment program is often detoxification (detox), the process of allowing the body to get rid of the substance. Detoxification under medical supervision allows the symptoms of withdrawal to be treated, but is not addiction treatment in and of itself. (Withdrawal is the sick, sometimes unbearable feeling that people have when trying to stop or cut down on a substance they have become addicted to or have been taking for a long time.)The type of withdrawal symptoms and how long they last vary with the substance abused. For example, withdrawal from certain stimulants may lead to fatigue, depression, and sleep problems. Unsupervised withdrawal from barbiturates and benzodiazepines can be dangerous. |
|
What are the treatments for Prescription and Illicit Drug Abuse ? | Different types of medications may be useful at different stages of treatment to help a person stop abusing a substance, stay in treatment, focus on learning new behavioral skills, and avoid relapse. Currently, medications are available to treat addiction to opiates, nicotine, and alcohol, but none are yet approved for treating addiction to stimulants, marijuana, or depressants. Medications for substance abuse treatment help the brain adjust to the absence of the abused substance. These medications act slowly to stave off drug cravings and prevent relapse. For example, buprenorphine, marketed as Subutex or Suboxone, is prescribed by approved physicians to treat people who are addicted to opiate drugs, such as painkillers or heroin. Buprenorphine is useful in the short-term detoxification process by helping ease withdrawal symptoms and in the long-term by staving off cravings and helping prevent relapse.

What are the treatments for Prescription and Illicit Drug Abuse ? | Behavioral treatment helps people change the way they think about the abused substance and teaches them how to handle or avoid situations that trigger strong drug cravings. Behavioral therapies can make treatment medications more effective, help people stay in treatment longer, and prevent relapse. There are four main types of behavioral treatments. - Cognitive behavioral therapy seeks to help people recognize, avoid, and cope with situations in which they are most likely to abuse substances.

|
What are the treatments for Prescription and Illicit Drug Abuse ? | Recovering from addiction is hard. Even with treatment, many people return to substance abuse, sometimes months or years after having stopped drug use. This is commonly referred to as relapse. As with most chronic diseases, relapse in addiction is not unusual, and signals a need to restart, adjust, or modify the treatment. |

What is (are) Problems with Smell ? | Our sense of smell helps us enjoy life. We delight in the aromas of our favorite foods or the fragrance of flowers. Our sense of smell also is a warning system, alerting us to danger signals such as a gas leak, spoiled food, or a fire. Any loss in our sense of smell can have a negative effect on our quality of life. It also can be a sign of more serious health problems. Aging and Smell Loss Problems with smell increase as people get older, and they are more common in men than women. In one study, nearly one-quarter of men ages 6069 had a smell disorder, while about 11 percent of women in that age range reported a problem. Many older people are not even aware that they have a problem with their sense of smell because the changes occur gradually over several years. They may not even notice that they are experiencing a loss of smell until there is an incident in which they don't detect food that has spoiled or the presence of dangerous smoke. How Our Sense of Smell Works The sense of smell, or olfaction, is part of our chemical sensing system, along with the sense of taste. Normal smell occurs when odors around us, like the fragrance of flowers or the smell of baking bread, stimulate the specialized sensory cells, called olfactory sensory cells. Olfactory sensory cells are located in a small patch of tissue high inside the nose. Odors reach the olfactory sensory cells in two pathways. The first pathway is by inhaling, or sniffing, through your nose. When people think about smell, they generally think of this pathway. The second pathway is less familiar. It is a channel that connects the roof of the throat region to the nose. When we chew our food, aromas are released that access olfactory sensory cells through this channel. If you are congested due to a head cold or sinus infection, this channel is blocked, which temporarily affects your ability to appreciate the flavors of food. Types of Smell Disorders People who experience smell disorders either have a decrease in their ability to smell or changes in the way they perceive odors. Total smell loss is relatively rare, but a decrease in the sense of smell occurs more often, especially in older adults. A decreased sense of smell may be temporary and treatable with medication. There are several types of smell disorders depending on how the sense of smell is affected. - Some people have hyposmia, which occurs when their ability to detect certain odors is reduced. - Other people can't detect odor at all, which is called anosmia. - Sometimes a loss of smell can be accompanied by a change in the perception of odors. This type of smell disorder is called dysosmia. Familiar odors may become distorted, or an odor that usually smells pleasant instead smells foul. - Still others may perceive a smell that isn't present at all, which is called phantosmia. - Smell loss due to aging is called presbyosmia. Some people have hyposmia, which occurs when their ability to detect certain odors is reduced. Other people can't detect odor at all, which is called anosmia. Sometimes a loss of smell can be accompanied by a change in the perception of odors. This type of smell disorder is called dysosmia. Familiar odors may become distorted, or an odor that usually smells pleasant instead smells foul. Still others may perceive a smell that isn't present at all, which is called phantosmia. Smell loss due to aging is called presbyosmia. Smell Loss May Signal Other Conditions Problems with our chemical senses may be a sign of other serious health conditions. A smell disorder can be an early sign of Parkinsons disease, Alzheimers disease, or multiple sclerosis. It can also be related to other medical conditions, such as obesity, diabetes, hypertension, and malnutrition. Getting a diagnosis early will help an individual deal better with the underlying condition or disease. Smell and Taste Smell and taste are closely linked in the brain, but are actually distinct sensory systems. True tastes are detected by taste buds on the tongue and the roof of the mouth, as well as in the throat region, and are limited to sweet, salty, sour, bitter, savory and perhaps a few other sensations. The loss of smell is much more common than the loss of taste, and many people mistakenly believe they have a problem with taste, when they are really experiencing a problem with their sense of smell. A loss in taste or smell is diagnosed by your doctor using special taste and smell tests. Smell Loss and Eating Habits When smell is impaired, people usually have problems appreciating the subtle flavors of food, and say that food is less enjoyable. Some people change their eating habits. Some may eat too little and lose weight while others may eat too much and gain weight. Either way, there may be a long-term impact on one's overall health. Loss of smell may also cause us to eat too much sugar or salt to make our food taste better. This can be a problem for people with certain medical conditions, such as diabetes or high blood pressure. In severe cases, loss of smell can lead to depression. Hazards of Smell Loss Research shows that people with a total or partial loss of smell are almost twice as likely as people with normal smell to have certain kinds of accidents. The most common types of accidents in order of frequency involve - cooking - eating or drinking spoiled foods or toxic substances - failing to detect gas leaks or fires cooking eating or drinking spoiled foods or toxic substances failing to detect gas leaks or fires If you think you have a problem with your sense of smell, see your doctor. |

What causes Problems with Smell ? | Problems with smell happen for many reasons, some clearer than others. Loss of smell may be permanent or temporary, depending on the cause. Effects of Aging As with vision and hearing, people gradually lose their ability to smell as they get older. Smell that declines with age is called presbyosmia and is not preventable. Age is only one of the many reasons that problems with smell can occur. Most people who develop a problem with smell have recently had an illness or injury. Common Causes The common causes of smell disorders are - sinus and upper respiratory infections - aging - smoking - nasal polyps - head injury - allergies - hormonal disturbances - dental problems - exposure to certain chemicals - numerous medications - radiation for treatment of head and neck cancers - diseases of the nervous system. sinus and upper respiratory infections aging smoking nasal polyps head injury allergies hormonal disturbances dental problems exposure to certain chemicals numerous medications radiation for treatment of head and neck cancers diseases of the nervous system. Sinus and Upper Respiratory Infections. The most common causes of smell problems are the common cold and chronic nasal or sinus infection. Respiratory infections such as the flu can lead to smell disorders. Swollen sinuses and nasal passages often result in problems with smell because the odors in the air do not have good access to the olfactory sensory cells. These conditions may cause total or partial loss of smell. The problem usually diminishes or goes away when the underlying medical condition clears up. Aging. Problems with smell become more common as people get older. A person's sense of smell generally declines when he or she is over 60. Smoking. Tobacco smoking is the most concentrated form of pollution that most people are exposed to. It impairs the ability to identify and enjoy odors. Nasal Polyps. Loss of smell can be caused by nasal polyps, which are small, non-cancerous growths in the nose or sinuses that can block the ability of odors to reach olfactory sensory cells high up in the nose. In rare cases, benign non-malignant tumors grow on the olfactory nerves leading to the brain, causing a loss of smell. Previous surgery or trauma to the head can impair your sense of smell because the olfactory nerves may be cut, blocked, or physically damaged. Automobile accidents are among the most frequent causes of trauma to the face and head. Allergies. If your smell disorder is caused by allergies and seasonal nasal congestion, you should avoid allergens, such as ragweed, grasses, and pet dander. Exposure to Certain Chemicals. Sometimes exposure to certain chemicals, such as insecticides and solvents, can permanently damage the sense of smell. Medications. If you are taking certain medicines, you may notice a change in your ability to smell. Certain medications, including some common antibiotics and antihistamines, can cause problems with smell. The sense of smell usually returns to normal when you stop taking the medicine. Radiation Treatment. People with head and neck cancers who receive radiation treatment to the nose and mouth regions commonly experience problems with their sense of smell and taste as an unfortunate side effect. Older people who have lost their larynx or voice box commonly complain of poor ability to smell and taste. Diseases of the Nervous System. Sometimes a problem with smell can be a sign of a more serious health problem. This might include diseases of the nervous system, such as Parkinson's disease or Alzheimer's disease. Loss of smell may be the first sign that something is wrong. Check with your doctor if you've been experiencing a problem with your sense of smell for a while. You may be able to prevent or get early treatment for a more serious health problem. |

What are the symptoms of Problems with Smell ? | A Reduced Sense of Smell There are several types of smell disorders depending on how the sense of smell is affected. People who have smell disorders experience either a loss in their ability to smell or changes in the way they perceive odors. Some people have hyposmia, which occurs when their ability to detect certain odors is reduced. This smell disorder is common in people who have upper respiratory infections or nasal congestion. This is usually temporary and goes away when the infection clears up. If You Can't Detect Odor at All Other people can't detect odor at all, which is called anosmia. This type of smell disorder is sometimes the result of head trauma in the nose region, usually from an automobile accident or chronic nasal or sinus infections. It can sometimes be caused by aging. In rare cases, anosmia is inherited. If Your Sense of Smell Is Distorted Sometimes a loss of smell can be accompanied by a change in the perception of odors. This type of smell disorder is called dysosmia. Familiar odors may become distorted, or an odor that usually smells pleasant instead smells foul. Sometimes people with this type of smell disorder also experience headaches, dizziness, shortness of breath, or anxiety. Still others may perceive a smell that isn't present at all, which is called phantosmia. Questions To Ask Yourself If you think you have a problem with your sense of smell, try to identify and record the circumstances at the time you first noticed the problem. Ask yourself the following questions: - When did I first become aware of it? - Did I have a cold or the flu? - Did I have a head injury? - Was I exposed to air pollutants, pollens, pet dander, or dust to which I might be allergic? - Is this a recurring problem? - Does it come at any special time, like during the hay fever season? When did I first become aware of it? Did I have a cold or the flu? Did I have a head injury? Was I exposed to air pollutants, pollens, pet dander, or dust to which I might be allergic? Is this a recurring problem? Does it come at any special time, like during the hay fever season? Bring this information with you when you visit your physician. Also, be prepared to tell him or her about your general health and any medications you are taking. Talking With Your Doctor Diagnosis by a doctor is important to identify and treat the underlying cause of a potential smell disorder. Your doctor may refer you to an otolaryngologist, a specialist in diseases of the ear, nose, and throat. An accurate assessment of a smell disorder will include, among other things, - a physical examination of the ears, nose, and throat - a review of your health history, such as exposure to toxic chemicals or injury, and - a smell test supervised by a health care professional. a physical examination of the ears, nose, and throat a review of your health history, such as exposure to toxic chemicals or injury, and a smell test supervised by a health care professional. Tests for Smell Disorders Some tests measure the smallest amount of odor you can detect. You also may receive a "scratch and sniff" test to determine how well you can identify various odors from a list of possibilities. In this test, the odor is embedded in a circular pad on a piece of paper and released when scratched. In this way, doctors can determine whether a person has a decreased ability to smell (hyposmia), the inability to detect any odors (anosmia), or another kind of smell disorder. In some cases, your doctor may need to perform a nasal examination with a nasal endoscope, an instrument that illuminates and magnifies the areas of the nose where the problem may exist. This test can help identify the area and extent of the problem and help your doctor select the right treatment. If your doctor suspects that upper regions of the nose and nasal sinuses that can't be seen by an endoscope are involved, he or she may order a specialized X-ray procedure, usually a CT scan, to look further into the nose and sinuses. When to See the Doctor If you think you have a smell disorder, see your doctor. Diagnosis of a smell disorder is important because once the cause is found, your doctor may be able to treat your smell disorder. Many types of smell problems are reversible, but if they are not, counseling and self-help techniques may help you cope. |

What are the treatments for Problems with Smell ? | Relief is Possible Although there is no treatment for presbyosmia -- loss of smell due to aging -- relief from smell disorders is possible for many older people. Depending on the cause of your problem with smell, your doctor may be able to treat it or suggest ways to cope with it. Recovering the Ability To Smell Some people recover their ability to smell when they recover from the illness causing their loss of smell. Some people recover their sense of smell spontaneously, for no obvious reason. Other common causes of smell loss, such as the common cold or seasonal allergies, are usually temporary. Smell is regained by waiting for the illness to run its course. In some cases, nasal obstructions, such as polyps, can be removed to restore airflow through the nasal passages and restore the sense of smell. If your smell disorder cant be successfully treated, you might want to seek counseling to help you adjust. Ask About Your Medications Sometimes a certain medication causes a smell disorder, and improvement occurs when the medicine causing the problem is stopped or changed. If you take medications, ask your doctor if they can affect your sense of smell. If so, ask if you could substitute other medications or reduce the dose. Your doctor will work with you to get the medicine you need while trying to reduce unwanted side effects. Medications That May Help Your doctor may suggest oral steroid medications such as prednisone, which is usually used for a short period of time, or topical steroid sprays, which can be used for longer periods of time. Antibiotics are also used to treat nasal infections. The effectiveness of both steroids and antibiotics depends greatly on the severity and duration of the nasal swelling or infection. Often relief is temporary. Occasionally, the sense of smell returns to normal on its own without any treatment. Steps You Can Take If you have a problem with smell, there are some things you can do. - Wait it out. If you have had a cold with a stuffy nose, chances are in a few days your sense of smell will return. However, you should not wait to see your doctor if you think something more serious has caused your loss of smell or you have had the problem for a while. Loss of smell can sometimes mean a more serious condition exists. Wait it out. If you have had a cold with a stuffy nose, chances are in a few days your sense of smell will return.

If your sense of smell seems to have disappeared or changed, or if you've noticed the problem for a while, see your doctor for help. Sometimes, especially with a sinus infection, taking antibiotics for a short period of time may remedy the problem. If there is a blockage or you have a chronic sinus condition, outpatient surgery may be called for. Check with your doctor.

If there is a blockage or you have a chronic sinus condition, outpatient surgery may be called for. If Your Smell Loss Is Permanent If you do not regain your sense of smell, there are things you should do to ensure your safety. Take extra precautions to avoid eating food that may have spoiled. If you live with other people, ask them to smell the food to make sure it is fresh. People who live alone should discard food if there is a chance it is spoiled. Other home safety measures include installing smoke alarms and gas detectors. For those who wish to have additional help, there may be support groups in your area. These are often associated with smell and taste clinics in medical school hospitals. Some online bulletin boards also allow people with smell disorders to share their experiences. Not all people with smell disorders will regain their sense of smell, but most can learn to live with it. Ongoing Research The National Institute on Deafness and Other Communication Disorders (NIDCD) supports basic and clinical investigations of smell and taste disorders at its laboratories in Bethesda, Md. and at universities and chemosensory research centers across the country. These chemosensory scientists are exploring how to - promote the regeneration of sensory nerve cells - understand the effects of the environment (such as gasoline fumes, chemicals, and extremes of humidity and temperature) on smell and taste - prevent the effects of aging on smell and taste - develop new diagnostic tests for taste and smell disorders - understand associations between smell disorders and changes in diet and food preferences in the elderly or among people with chronic illnesses. promote the regeneration of sensory nerve cells understand the effects of the environment (such as gasoline fumes, chemicals, and extremes of humidity and temperature) on smell and taste prevent the effects of aging on smell and taste develop new diagnostic tests for taste and smell disorders understand associations between smell disorders and changes in diet and food preferences in the elderly or among people with chronic illnesses. |

How to prevent Problems with Smell ? | Problems with smell that occur with aging are not preventable. However, you can protect yourself against other causes of smell loss with these steps. - Treat Sinus and Nasal Conditions. Swollen sinuses and nasal passages may cause total or partial loss of smell. Your doctor may prescribe an antibiotic or anti-inflammatory drug to reduce nasal swelling from chronic sinus infections, a major cause of smell loss. Treat Sinus and Nasal Conditions.

What causes Problems with Smell ? | In rare cases, certain medicines such as antibiotics or antihistamines may cause a change in your ability to smell. If you are taking these medications and notice a change in your sense of smell, talk to your doctor. You may be able to adjust or change your medicine to one that will not cause a problem with smell. |

How to diagnose Problems with Smell ? | Scientists have developed tests to determine the nature and extent of a person's smell disorder. Tests measure the smallest amount of odor patients can detect as well as how accurately a person can identify different smells. An easily administered "scratch and sniff" test allows a person to scratch pieces of paper treated to release different odors, sniff them, and try to identify each odor from a list of possibilities. In this way, doctors can determine whether a person has a decreased ability to smell (hyposmia), the inability to detect any odors (anosmia), or another kind of smell disorder. In some cases, your doctor may need to perform a nasal examination with a nasal endoscope, an instrument that illuminates and magnifies the areas of the nose where the problem may exist. This test can help identify the area and extent of the problem and help your doctor select the right treatment. If your doctor suspects that upper regions of the nose and nasal sinuses that can't be seen by an endoscope are involved, he or she may order a specialized X-ray procedure, usually a CT scan, to look further into the nose and sinuses. |

What are the treatments for Problems with Smell ? | Depending on the cause of your smell disorder, your doctor may be able to treat your problem or suggest ways to cope with it. If a certain medication is the cause of the disorder, ask your doctor if you could substitute other medications or reduce the dose. Your doctor will work with you to get the medicine you need while trying to reduce unwanted side effects. Some patients with respiratory infections or allergies regain their sense of smell when the illness or condition is over. Often, correcting a general medical problem also can restore the sense of smell. For patients with nasal obstructions, such as polyps, or other inflammatory conditions of the nose or sinuses, medical treatments or surgery can restore the sense of smell. Occasionally, the sense of smell returns to normal on its own, without any treatment. Your doctor may suggest oral steroid medications such as prednisone, which is usually used for a short period of time, or topical steroid sprays, which can be used for longer periods of time. Antibiotics are also used to treat nasal infections. The effectiveness of both steroids and antibiotics depends greatly on the severity and duration of the nasal swelling or infection. Often relief is temporary. |

what research (or clinical trials) is being done for Problems with Smell ? | The National Institute on Deafness and Other Communication Disorders (NIDCD) supports basic and clinical investigations of smell and taste disorders at its laboratories in Bethesda, Md. and at universities and chemosensory research centers across the country. These chemosensory scientists are exploring how to - promote the regeneration of sensory nerve cells - understand the effects of the environment (such as gasoline fumes, chemicals, and extremes of humidity and temperature) on smell and taste - prevent the effects of aging on smell and taste - develop new diagnostic tests for taste and smell disorders - understand associations between smell disorders and changes in diet and food preferences in the elderly or among people with chronic illnesses. promote the regeneration of sensory nerve cells understand the effects of the environment (such as gasoline fumes, chemicals, and extremes of humidity and temperature) on smell and taste prevent the effects of aging on smell and taste develop new diagnostic tests for taste and smell disorders understand associations between smell disorders and changes in diet and food preferences in the elderly or among people with chronic illnesses. |

What is (are) Heart Failure ? | In heart failure, the heart cannot pump enough blood to meet the body's needs. In some cases, the heart cannot fill with enough blood. In other cases, the heart can't pump blood to the rest of the body with enough force. Some people have both problems. Heart failure develops over time as the pumping action of the heart gets weaker. It can affect either the right, the left, or both sides of the heart. Heart failure does not mean that the heart has stopped working or is about to stop working. When heart failure affects the left side of the heart, the heart cannot pump enough oxygen-rich blood to the rest of the body. When heart failure affects the right side, the heart cannot pump enough blood to the lungs, where it picks up oxygen. The Heart's Pumping Action In normal hearts, blood vessels called veins bring oxygen-poor blood from the body to the right side of the heart. It is then pumped through the pulmonary artery to the lungs, picking up oxygen. From there, the blood returns to the left side of the heart. Then it is pumped through a large artery called the aorta that distributes blood throughout the body. When the heart is weakened by heart failure, blood and fluid can back up into the lungs, and fluid builds up in the feet, ankles, and legs. People with heart failure often experience tiredness and shortness of breath. Heart Failure is Serious Heart failure is a serious and common condition. Scientists estimate that 5 million people in the U.S. have heart failure and that number is growing. It contributes to 300,000 deaths each year. Heart failure is most common in those age 65 and older and it is the number one reason older people are hospitalized. Other Names for Heart Failure Heart failure can also be called congestive heart failure, systolic heart failure, diastolic heart failure, left-sided heart failure, or right-sided heart failure. |
|
What causes Heart Failure ? | Heart failure is caused by other diseases or conditions that damage the heart muscle such as coronary artery disease (including heart attacks), diabetes, and high blood pressure. Treating these problems can prevent or improve heart failure. Coronary Artery Disease Coronary artery disease is a leading cause of death in men and women. It happens when the arteries that supply blood to the heart become hardened and narrowed. High Blood Pressure High blood pressure is the force of blood pushing against the walls of the arteries. If this pressure rises and stays high over time, it can weaken your heart and lead to plaque buildup, which can then lead to heart failure. Diabetes Diabetes is characterized by having too much glucose, or sugar, in the blood for a long time. This can cause heart problems because high blood glucose can damage parts of the body such as the heart and blood vessels. This damage weakens the heart, often leading to heart failure. Other Diseases Other diseases and conditions also can lead to heart failure, such as - Cardiomyopathy (KAR-de-o-mi-OP-ah-thee), or heart muscle disease. Cardiomyopathy may be present at birth or caused by injury or infection. - Heart valve disease. Problems with the heart valves may be present at birth or caused by infection, heart attack, or damage from heart disease. - Arrhythmias (ah-RITH-me-ahs), or irregular heartbeats. These heart problems may be present at birth or caused by heart disease or heart defects. - Congenital (kon-JEN-ih-tal) heart defects. These problems with the heart's structure are present at birth. Cardiomyopathy (KAR-de-o-mi-OP-ah-thee), or heart muscle disease. Cardiomyopathy may be present at birth or caused by injury or infection. Heart valve disease. Problems with the heart valves may be present at birth or caused by infection, heart attack, or damage from heart disease. Arrhythmias (ah-RITH-me-ahs), or irregular heartbeats. These heart problems may be present at birth or caused by heart disease or heart defects. Congenital (kon-JEN-ih-tal) heart defects. These problems with the heart's structure are present at birth. Other Factors Other factors also can injure the heart muscle and lead to heart failure. Examples include - treatments for cancer, such as radiation and chemotherapy - thyroid disorders (having either too much or too little thyroid hormone in the body) - alcohol abuse or cocaine and other illegal drug use - HIV/AIDS - too much vitamin E. treatments for cancer, such as radiation and chemotherapy thyroid disorders (having either too much or too little thyroid hormone in the body) alcohol abuse or cocaine and other illegal drug use HIV/AIDS too much vitamin E. Sleep Apnea Heart damage from obstructive sleep apnea may worsen heart failure. Sleep apnea is a common disorder in which you have one or more pauses in breathing or shallow breaths while you sleep. Sleep apnea can deprive your heart of oxygen and increase its workload. Treating this sleep disorder might improve heart failure. Who Is at Risk? Heart failure can happen to almost anyone. It is the number one reason for hospitalization for people over age 65. Heart failure is more common in - people who are 65 years old or older - African-Americans - people who are overweight - people who have had a heart attack - men. people who are 65 years old or older African-Americans people who are overweight people who have had a heart attack men. Aging can weaken the heart muscle. Older people also may have had diseases for many years that led to heart failure. African Americans are more likely to have heart failure than people of other races. They're also more likely to have symptoms at a younger age, have more hospital visits due to heart failure, and die from heart failure. Excess weight puts strain on the heart. Being overweight also increases your risk of heart disease and type 2 diabetes. These diseases can lead to heart failure. A history of a heart attack puts people at greater risk for heart failure. Men have a higher rate of heart failure than women. |

Who is at risk for Heart Failure? ? | Preventing Heart Failure There are a number of things you can do to reduce the risk for coronary artery disease and heart failure. These things include - keeping your cholesterol levels healthy - keeping your blood pressure at a normal level - managing diabetes - maintaining a healthy weight - quitting smoking - limiting the amount of alcohol you drink - following a heart healthy diet - limiting the amount of sodium (salt) you consume - getting regular exercise - avoiding using illegal drugs. keeping your cholesterol levels healthy keeping your blood pressure at a normal level managing diabetes maintaining a healthy weight quitting smoking limiting the amount of alcohol you drink following a heart healthy diet limiting the amount of sodium (salt) you consume getting regular exercise avoiding using illegal drugs. Keep Your Cholesterol Levels Healthy Keeping your cholesterol levels healthy can help prevent coronary artery disease. Your goal for LDL, or "bad," cholesterol, depends on how many other risk factors you have. Risk factors include - being a cigarette smoker - having high blood pressure - having low HDL cholesterol - being 45 or older if you are a man and 55 or older if you are a woman - having a close relative who had coronary artery disease at an earlier-than-usual age (before age 55 for male relatives and before age 65 for female relatives). being a cigarette smoker having high blood pressure having low HDL cholesterol being 45 or older if you are a man and 55 or older if you are a woman having a close relative who had coronary artery disease at an earlier-than-usual age (before age 55 for male relatives and before age 65 for female relatives). Recommended LDL Cholesterol Goals - If you don't have coronary heart disease or diabetes and have one or no risk factors, your LDL goal is less than 160 mg/dL. - If you don't have coronary heart disease or diabetes and have two or more risk factors, your LDL goal is less than 130 mg/dL. - If you do have coronary heart disease or diabetes, your LDL goal is less than 100 mg/dL. - The goal for HDL, or "good," cholesterol is above 40 in men and above 50 in women. - The goal for triglycerides, another fat in the blood, is below 150. If you don't have coronary heart disease or diabetes and have one or no risk factors, your LDL goal is less than 160 mg/dL. If you don't have coronary heart disease or diabetes and have two or more risk factors, your LDL goal is less than 130 mg/dL. If you do have coronary heart disease or diabetes, your LDL goal is less than 100 mg/dL. The goal for HDL, or "good," cholesterol is above 40 in men and above 50 in women. The goal for triglycerides, another fat in the blood, is below 150. Learn how to control your cholesterol with TLC -- Therapeutic Lifestyle Changes. Keep Blood Pressure at a Normal Level High blood pressure causes the heart to get larger and work harder, which can then lead to heart failure. You should aim for a blood pressure level of 130/80 or below. Talk to your doctor about ways to lower your blood pressure. Get tips on how to control your blood pressure. Manage Diabetes If you have diabetes, its important to manage it properly. Diabetes is characterized by having too much glucose, or sugar, in the blood for a long time. This can cause heart problems because high blood glucose can damage parts of the body such as the heart and blood vessels. This damage weakens the heart, often leading to heart failure. See ways to manage your diabetes every day. Maintain a Healthy Weight Excess weight puts strain on the heart. Being overweight also increases your risk of heart disease and type 2 diabetes. These diseases can lead to heart failure. See a sensible approach to weight loss. Don't Smoke If you smoke, quit. For free help quitting, call a smoking quit line. See medications to help you quit. Follow a Heart Healthy Diet Heart-healthy foods include those high in fiber, such as oat bran, oatmeal, whole-grain breads and cereals, fruits, and vegetables. You can also maintain a heart-healthy diet by limiting foods that are high in saturated fat, trans-fat, and cholesterol, such as meats, butter, dairy products with fat, eggs, shortening, lard, and foods with palm oil or coconut oil. For more on healthy eating, see Eating Well As You Get Older. Limit the Amount of Alcohol You Drink In general, healthy men and women over age 65 should not drink more than three drinks a day or a total of seven drinks a week. Learn how alcohol affects you as get older. Limit the Amount of Sodium Sodium contributes to high blood pressure and fluid retention. Older adults should limit their intake of sodium to1,500 milligrams daily (about 2/3 tsp. of salt). See ways to cut back on your salt intake. Get Regular Exericse Studies show that people with heart disease, diabetes, and high blood pressure benefit from regular exercise. In fact, inactive people are nearly twice as likely to develop heart disease as those who are more active. Aim for at least 30 minutes a day of exercise. Check with your doctor before starting any exercise program. For information on exercise and older adults, see Benefits of Exercise or visit Go4Life, the exercise and physical activity campaign for older adults from the National Institute on Aging. |

What are the symptoms of Heart Failure ? | Common Symptoms The most common symptoms of heart failure include shortness of breath or difficulty breathing, feeling tired, and swelling. Swelling usually occurs in the ankles, feet, legs, and sometimes in the abdomen. Swelling is caused by fluid buildup in the body. The fluid buildup can lead to weight gain as well as a cough. The cough can be worse at night and when lying down. When symptoms first begin, you might feel tired or short of breath after routine physical activities, such as climbing stairs. As heart failure progresses, the symptoms get worse. You may feel tired or short of breath after performing simple activities, like getting dressed. |
|
How to diagnose Heart Failure ? | Diagnosing Heart Failure There is not one specific test to diagnose heart failure. Because the symptoms are common for other conditions, your doctor will determine if you have heart failure by doing a detailed medical history, an examination, and several tests. The tests will identify whether you have any diseases or conditions that can cause heart failure. They will also rule out any other causes of your symptoms and determine the amount of damage to your heart. During a physical examination, you can expect your doctor to listen to your heart for abnormal sounds and listen to your lungs for a buildup of fluid. Your doctor will also look for swelling in your ankles, feet, legs, abdomen, and in the veins in your neck If your doctor determines that you have signs of heart failure, he or she may order several tests. Diagnostic Tests Tests that are given to determine heart failure include an electrocardiogram (EKG or ECG), a chest x-ray, and a BNP blood test. An EKG or ECG -- electrocardiogram -- measures the rate and regularity of your heartbeat. This test can also show if you have had a heart attack and whether the walls of your heart have thickened. A chest X-ray takes a picture of your heart and lungs. It will show whether your heart is enlarged or your lungs have fluid in them, both signs of heart failure. A BNP blood test measures the level of a hormone in your blood called BNP -- brain natriuretic peptide -- that increases in heart failure. Once these initial tests have been performed, your doctor may decide to send you to a cardiologist, a specialist in the diagnosis and treatment of heart disease. A cardiologist will perform a physical exam and may order other tests. Other Tests Tests that can identify the cause of heart failure include an echocardiogram, a Holter monitor, and an exercise stress test. An echocardiogram is one of the most useful tests for diagnosing heart failure. This test uses sound waves to create a picture of the heart and shows how well the heart is filling with blood. Your doctor uses this test to determine whether any areas of your heart are damaged. A Holter monitor, which is a small box that is attached to patches placed on your chest. The monitor, which is worn for 24 hours, provides a continuous recording of heart rhythm during normal activity. An exercise stress test captures your EKG and blood pressure before, during, or after exercise to see how your heart responds to exercise. This test tells doctors how your heart responds to activity. |
|
What are the treatments for Heart Failure ? | There is no cure for heart failure, but it can be controlled by treating the underlying conditions that cause it. Treatment for heart failure will depend on the type and stage of heart failure (the severity of the condition). The goals for treatment of all stages of heart failure are to reduce symptoms, treat the cause (such as heart disease, high blood pressure, or diabetes), stop the disease from worsening, and prolong life. Treatments for Heart Failure Treatments for heart failure include - lifestyle changes - medications - specialized care for those who are in the advanced stages. lifestyle changes medications specialized care for those who are in the advanced stages. Treatment for heart failure will reduce the chances that you will have to go to the hospital and make it easier for you to do the things you like to do. It is very important that you follow your treatment plan by keeping doctor appointments, taking medications, and making lifestyle changes. |

What is (are) Lung Cancer ? | How Tumors Form The body is made up of many types of cells. Normally, cells grow, divide, and produce more cells as needed to keep the body healthy and functioning properly. Sometimes, however, the process goes wrong and cells become abnormal, forming more cells in an uncontrolled way. These extra cells form a mass of tissue, called a growth or tumor. Tumors can be benign, which means not cancerous, or malignant, which means cancerous. Lung cancer occurs when a tumor forms in the tissue of the lung. The Leading Cause of Cancer Death Lung cancer is the leading cause of cancer death in men and women in the United States. Experts estimate that over 200,000 new cases of lung cancer will be diagnosed each year slightly more cases in men than women. Over 150,000 Americans die of the disease each year. Lung cancer occurs most often between the ages of 55 and 65. (Watch the videos on this page to learn more about lung cancer. To enlarge the videos, click the brackets in the lower right-hand corner of the video screen. To reduce the videos, press the Escape (Esc) button on your keyboard.) Two Major Types of Lung Cancer There are two major types of lung cancer -- non-small cell lung cancer and small cell lung cancer. Each type of lung cancer grows and spreads in different ways, and each is treated differently. - Non-small cell lung cancer is more common than small cell lung cancer. - Small cell lung cancer grows more quickly and is more likely to spread to other organs in the body. Non-small cell lung cancer is more common than small cell lung cancer. Small cell lung cancer grows more quickly and is more likely to spread to other organs in the body. Learn more about non-small cell lung cancer. Learn more about small cell lung cancer. Lung Cancer Can Spread Lung cancer may spread to the lymph nodes or other tissues in the chest, including the lung opposite to where it originated. It may also spread to other organs of the body, such as the bones, brain, or liver. When cancer spreads from its original location in the lung to another part of the body such as the brain, it is called metastatic lung cancer, not brain cancer. Doctors sometimes call this distant disease. Smoking and Lung Cancer Lung cancer would occur much less often if people did not smoke. The good news is that smoking is not as popular as it used to be. In 1965 about 42 percent of all adults smoked, but as of 2012, slightly less than 17 percent of people 18 and older smoked cigarettes. Also, since the 1990s there has been a steady drop in lung cancer deaths among men, mainly because fewer men are smoking, and since the turn of the century, lung cancer deaths in women have been slowly declining. Cigarette smoking rates had been dropping steadily in the 1990s and had started to level off at the start of the 21st century but the latest figures show a continued decline. The bad news is that other forms of tobacco use have shown some revival, but mainly in younger populations. The bad news is that smoking rates, which were dropping, have stopped declining in recent years. Smoking by young adults actually increased by 73 percent in the 1990s but has shown a downturn or leveling off in the past few years. |

What causes Lung Cancer ? | Tobacco Products and Cancer Using tobacco products has been shown to cause cancer. In fact, smoking tobacco, using smokeless tobacco, and being exposed regularly to secondhand tobacco smoke are responsible for a large number of cancer deaths in the U.S. each year. Cigarette Smoking Causes Lung Cancer Cigarette smoking is the number one cause of lung cancer. Scientists have reported widely on the link between cancer and smoking since the 1960s. Since then, study after study has provided more proof that cigarette smoking is the primary cause of lung cancer. Before cigarette smoking became popular after World War I, doctors rarely, if ever, saw patients with lung cancer. But today, lung cancer is the leading cause of death by cancer. Over 85 percent of people with lung cancer developed it because they smoked cigarettes. If You Smoke If you smoke cigarettes, you are at much higher risk for lung cancer than a person who has never smoked. The risk of dying from lung cancer is 23 times higher for men who smoke and 13 times higher for women who smoke than for people who have never smoked. Lung cancer can affect young and old alike. Stopping smoking greatly reduces your risk for developing lung cancer. After you stop, your risk levels off. Ten years after the last cigarette, the risk of dying from lung cancer drops by 50 percent -- which does not mean, however, that risk is eliminated. (Watch the videos on this page to learn more about lung cancer, smoking and older adults. To enlarge the videos, click the brackets in the lower right-hand corner of the video screen. To reduce the videos, press the Escape (Esc) button on your keyboard.) Smoking cigars and pipes also puts you at risk for lung cancer. Cigar and pipe smokers have a higher risk of lung cancer than nonsmokers. Even cigar and pipe smokers who do not inhale are at increased risk for lung, mouth, and other types of cancer. The likelihood that a smoker will develop lung cancer is related to the age smoking began; how long the person smoked; the number of cigarettes, pipes, or cigars smoked per day; and how deeply the smoker inhaled. Learn about lung cancer prevention. Other Factors That Increase Your Risk - Many studies suggest that non-smokers who are exposed to environmental tobacco smoke, also called secondhand smoke, are at increased risk of lung cancer. Secondhand smoke is the smoke that non-smokers are exposed to when they share air space with someone who is smoking. Tobacco smoke contains more than 7,000 chemicals, including hundreds that are toxic and about 70 that can cause cancer. Since 1964, approximately 2,500,000 nonsmokers have died from health problems caused by exposure to secondhand smoke. - Exposure to radon can put a person at risk for lung cancer, too. People who work in mines may be exposed to this invisible, odorless, and radioactive gas that occurs naturally in soil and rocks. It is also found in houses in some parts of the country. A kit available at most hardware stores allows homeowners to measure radon levels in their homes. - Another substance that can contribute to lung cancer is asbestos. Asbestos has been used in shipbuilding, asbestos mining and manufacturing, insulation work, and brake repair, although products with asbestos have been largely phased out over the past several decades. If inhaled, asbestos particles can lodge in the lungs, damaging cells and increasing the risk for lung cancer. Many studies suggest that non-smokers who are exposed to environmental tobacco smoke, also called secondhand smoke, are at increased risk of lung cancer. Secondhand smoke is the smoke that non-smokers are exposed to when they share air space with someone who is smoking. Tobacco smoke contains more than 7,000 chemicals, including hundreds that are toxic and about 70 that can cause cancer.

What are the symptoms of Lung Cancer ? | Common Signs and Symptoms When lung cancer first develops, there may be no symptoms at all. But if the cancer grows, it can cause changes that people should watch for. Common signs and symptoms of lung cancer include: - a cough that doesn't go away and gets worse over time - constant chest pain - coughing up blood - shortness of breath, wheezing, or hoarseness - repeated problems with pneumonia or bronchitis - swelling of the neck and face - loss of appetite or weight loss - fatigue. a cough that doesn't go away and gets worse over time constant chest pain coughing up blood shortness of breath, wheezing, or hoarseness repeated problems with pneumonia or bronchitis swelling of the neck and face loss of appetite or weight loss fatigue. These symptoms may be caused by lung cancer or by other conditions. It is important to check with a doctor if you have symptoms because only a doctor can make a diagnosis. Don't wait to feel pain. Early cancer usually doesn't cause pain. Tests for Lung Cancer To better understand a persons chance of developing lung cancer, a doctor first evaluates a person's medical history, smoking history, their exposure to environmental and occupational substances, and family history of cancer. The doctor also performs a physical exam and may order a test to take an image of the chest or other tests. Seeing a spot on an image is usually how a doctor first suspects that lung cancer may be present. If lung cancer is suspected, the doctor may order a test called sputum cytology. This is a simple test where, under a microscope, a doctor examines a sample of mucous cells coughed up from the lungs under a microscope to see if cancer is present. Biopsies to Detect Lung Cancer But to confirm the presence of lung cancer, the doctor must examine fluid or tissue from the lung. This is done through a biopsy -- the removal of a small sample of fluid or tissue for examination under a microscope by a pathologist. A biopsy can show whether a person has cancer. A number of procedures may be used to obtain this tissue. - Bronchoscopy -- The doctor puts a bronchoscope -- a thin, lighted tube -- into the mouth or nose and down through the windpipe to look into the breathing passages. Through this tube, the doctor can collect cells or small samples of tissue. - Needle Aspiration -- The doctor numbs the chest area and inserts a thin needle into the tumor to remove a sample of tissue. - Thoracentesis - Using a needle, the doctor removes a sample of the fluid that surrounds the lungs to check for cancer cells. - Thorascopy or Thoracotomy -- Surgery to open the chest is sometimes needed to diagnose lung cancer. This procedure is a major operation performed in a hospital.

Thorascopy or Thoracotomy -- Surgery to open the chest is sometimes needed to diagnose lung cancer. This procedure is a major operation performed in a hospital. Other Tests Doctors use imaging methods such as a spiral CT scan (also commonly known as helical CT) to look for signs of cancer. A CT scan, also known as computerized tomography scan, is a series of detailed pictures of areas inside the body. Other tests can include removal of lymph nodes for examination under a microscope to check for cancer cells. Lymph nodes are small, bean-shaped structures found throughout the body. They filter substances in a fluid called lymph and help fight infection and disease. |

What are the treatments for Lung Cancer ? | There are many treatment options for lung cancer, mainly based on the extent of the disease. The choice of treatment depends on your age and general health, the stage of the cancer, whether or not it has spread beyond the lung, and other factors. If tests show that you have cancer, you should talk with your doctor and make treatment decisions as soon as possible. Studies show that early treatment leads to better outcomes. Working With a Team of Specialists A team of specialists often treats people with cancer. The team will keep the primary doctor informed about the patient's progress. The team may include a medical oncologist who is a specialist in cancer treatment, a surgeon, a radiation oncologist who is a specialist in radiation therapy, a thoracic surgeon who is a specialist in operating on organs in the chest, including the lungs, and others. Before starting treatment, you may want another doctor to review the diagnosis and treatment plan. Some insurance companies require a second opinion. Others may pay for a second opinion if you request it. Clinical Trials for Lung Cancer Some lung cancer patients take part in studies of new treatments. These studies, called clinical trials, are designed to find out whether a new treatment is safe and effective. Often, clinical trials compare a new treatment with a standard one so that doctors can learn which is more effective. People with lung cancer who are interested in taking part in a clinical trial should talk with their doctor. The U.S. National Institutes of Health, through its National Library of Medicine and other Institutes, maintains a database of clinical trials at ClinicalTrials.gov.

What are the treatments for Lung Cancer ? | The choice of treatment depends on the type of lung cancer, whether it is non-small or small cell lung cancer, the size, location, the stage of the cancer, and the patient's general health. Doctors may suggest many different treatments or combinations of treatments to control the cancer and/or improve the patient's quality of life. What Standard Treatments Do Here are some of the most common treatments for lung cancer. - Surgery is an operation to remove the cancer. Depending on the location of the tumor, the surgeon may remove a small part of the lung, a lobe of the lung, or the entire lung and possibly even part of the ribcage to get to the lung. - Chemotherapy uses anti-cancer drugs to kill cancer cells throughout the body. Doctors use chemotherapy to control cancer growth and relieve symptoms. Anti-cancer drugs are given by injection; through a catheter, a long thin tube temporarily placed in a large vein; or in pill form. - Targeted therapy is a type of treatment that uses drugs or other substances to attack specific cancer cells. - Radiation therapy uses high-energy beams to kill cancer cells and shrink tumors. An external machine delivers radiation to a limited area, affecting cancer cells only in that area. Doctors may use radiation before surgery to shrink a tumor or after surgery to destroy any cancer cells remaining in the treated area. Surgery is an operation to remove the cancer.

Doctors may use radiation before surgery to shrink a tumor or after surgery to destroy any cancer cells remaining in the treated area. Treating Non-Small Cell Lung Cancer Doctors treat patients with non-small cell lung cancer in several ways, and surgery is a common treatment. Cryosurgery, a treatment that freezes and destroys cancer tissue, may be used to control symptoms in the later stages of non-small cell lung cancer. Doctors may also use radiation therapy and chemotherapy to slow the progress of the disease and to manage symptoms. See more information about treatments for non-small cell lung cancer. Treating Small Cell Lung Cancer Small cell lung cancer spreads quickly. In many cases, cancer cells have already spread to other parts of the body when the disease is diagnosed. In order to reach cancer cells throughout the body, doctors almost always use chemotherapy. Treatment for small cell lung cancer may also include radiation therapy aimed at the tumor in the lung or tumors in other parts of the body, such as in the brain. Surgery is part of the treatment plan for a small number of patients with small cell lung cancer. Some patients with small cell lung cancer have radiation therapy to the brain even though no cancer is found there. This treatment, called prophylactic cranial irradiation or PCI, is given to prevent tumors from forming in the brain. See more information about treatments for small cell lung cancer. |

what research (or clinical trials) is being done for Lung Cancer ? | Researchers continue to look at new ways to combine, schedule, and sequence the use of chemotherapy, surgery, and radiation to treat lung cancer. Today, some of the most promising treatment approaches incorporate precision medicine. This approach first looks to see what genes may be mutated that are causing the cancer, and once these genes are identified, specific drugs may be available that target the mutations and treat the cancer directly without the harsh side-effects often found with conventional chemotherapy. Researchers are also constantly trying to come up with new ways to find and diagnose lung cancer in order to catch it and treat it in its earliest stages. The National Lung Screening Trial, or NLST, showed conclusively that spiral CT reduced the risk of dying by 20 percent compared to those who received a chest x-ray among heavy smokers Get more information on current lung cancer research. |

What is (are) Lung Cancer ? | The body is made up of many types of cells. Normally, cells grow, divide, and produce more cells as needed to keep the body healthy and functioning properly. Sometimes, however, the process goes wrong -- cells become abnormal and form more cells in an uncontrolled way. These extra cells form a mass of tissue, called a growth or tumor. Tumors can be benign, meaning not cancerous, or malignant, meaning cancerous. |
|
What is (are) Lung Cancer ? | Lung cancer occurs when malignant tumors form in the tissue of the lung. The lungs are a pair of sponge-like organs. The right lung has three sections, called lobes, and is larger than the left lung, which has two lobes. |
|
What is (are) Lung Cancer ? | There are two major types of lung cancer -- non-small cell lung cancer and small cell lung cancer. Each type of lung cancer grows and spreads in different ways, and each is treated differently. Non-small cell lung cancer is more common than small cell lung cancer. It generally grows and spreads slowly. Learn more about non-small cell carcinoma. Small cell lung cancer, sometimes called oat cell cancer, grows more quickly and is more likely to spread to other organs in the body. Learn more about small cell carcinoma. |
|
What causes Lung Cancer ? | Cigarette smoking is the number one cause of lung cancer. Scientists have reported widely on the link between cancer and smoking since the 1960s. Since then, study after study has provided more proof that cigarette smoking is the primary cause of lung cancer. Before cigarette smoking became popular after World War I, doctors rarely, if ever, saw patients with lung cancer. But today, lung cancer is the leading cause of death by cancer. Over 85 percent of people with lung cancer developed it because they smoked cigarettes. Using tobacco products has been shown to cause many types of cancer. In fact, smoking tobacco, using smokeless tobacco, and being exposed regularly to second-hand tobacco smoke are responsible for a large number of cancer deaths in the U.S. each year. |
|
Who is at risk for Lung Cancer? ? | Risk factors that increase your chance of getting lung cancer include - cigarette, cigar, and pipe smoking, which account for well over half of all cases of lung cancer - secondhand smoke - family history - HIV infection - environmental risk factors - beta carotene supplements in heavy smokers. cigarette, cigar, and pipe smoking, which account for well over half of all cases of lung cancer secondhand smoke family history HIV infection environmental risk factors beta carotene supplements in heavy smokers. |
|
Who is at risk for Lung Cancer? ? | If you smoke cigarettes, you are at much higher risk for lung cancer than a person who has never smoked. The risk of dying from lung cancer is 23 times higher for men who smoke and 13 times higher for women who smoke than for people who have never smoked. Stopping smoking greatly reduces your risk for developing lung cancer. But after you stop, the risk goes down slowly. Ten years after the last cigarette, the risk of dying from lung cancer drops by 50 percent.

|
What is (are) Lung Cancer ? | A person who has had lung cancer once is more likely to develop a second lung cancer compared to a person who has never had lung cancer. Second cancers arise in a different site than the original cancer. If the original cancer returns after treatment, it is considered recurrent, not a second cancer. Quitting smoking after lung cancer is diagnosed may prevent the development of a second lung cancer. |

How to diagnose Lung Cancer ? | Doctors can perform several tests to stage lung cancer. Staging means finding out how far the cancer has progressed. The following tests are used to stage lung cancer: - Computerized tomography or CAT scan is a computer linked to an x-ray machine that creates a series of detailed pictures of areas inside the body.

Magnetic resonance imaging, or MRI, is a powerful magnet linked to a computer that makes detailed pictures of areas inside the body. Radionuclide scanning uses a mildly radioactive substance to show whether cancer has spread to other organs, such as the liver. - A bone scan uses a small amount of a radioactive substance to show whether cancer has spread to the bones. - A mediastinoscopy or mediastinotomy can help show whether the cancer has spread to the lymph nodes in the chest by removing a tissue sample. The patient receives a general anesthetic for this procedure. A bone scan uses a small amount of a radioactive substance to show whether cancer has spread to the bones.

What is (are) Alcohol Use and Older Adults ? | Alcohol, also known as ethanol, is a chemical found in beverages like beer, wine, and distilled spirits such as whiskey, vodka, and rum. Through a process called fermentation, yeast converts the sugars naturally found in grains and grapes into the alcohol that is in beer and wine. Another process, called distillation, concentrates alcohol in the drink making it stronger, producing what are known as distilled spirits. |

What is (are) Alcohol Use and Older Adults ? | Blood alcohol concentration (BAC) measures the percentage of ethanolthe chemical name for alcohol in alcoholic beveragesin a persons blood. As you drink, you increase your blood alcohol concentration (BAC) level. The higher the BAC, the more impaired a person is. In all states, it is against the law for people to drive if their blood alcohol concentration is above .08. The effects of increased blood alcohol levels can include - reduced inhibitions - slurred speech - motor impairment - confusion - memory problems - concentration problems - coma - breathing problems - death. reduced inhibitions slurred speech motor impairment confusion memory problems concentration problems coma breathing problems death.

What are the symptoms of Alcohol Use and Older Adults ? | Its not always obvious that someone drinks too much. For older adults, clues to a possible alcohol problem include memory loss, depression, anxiety, poor appetite, unexplained bruises, falls, sleeping problems, and inattention to cleanliness or appearance. Answering "yes" to at least one of the following questions is also a sign of a possible drinking problem: - Have you ever felt you should cut down on your drinking? - Have people annoyed you by criticizing your drinking? - Have you ever felt bad or guilty about your drinking? - Have you ever had a drink first thing in the morning to steady your nerves or get rid of a hangover? Have you ever felt you should cut down on your drinking? Have people annoyed you by criticizing your drinking? Have you ever felt bad or guilty about your drinking? Have you ever had a drink first thing in the morning to steady your nerves or get rid of a hangover? If you answered yes to any of these questions, talk with your health care provider. Also seek help if you feel you are having drinking-related problems with your health, relationships, or work. |
|
What is (are) Alcohol Use and Older Adults ? | If a person drinks too much or too often he or she may develop an alcohol use disorder (AUD). An AUD can range in severity from mild to severe. On one end of this spectrum, drinking might cause sickness, depression, or sleeping problems. More severe symptoms include drinking more than intended or craving alcohol once youve stopped drinking. AUD can be a lifelong disease in which people have a strong need to drink, cannot control their drinking once they start, and over time need to drink greater and greater amounts of alcohol to get high. Older adults who develop a severe AUD become physically dependent on alcohol. When they stop drinking, they can get nauseated, sweaty, shaky, and restless. These withdrawal symptoms can cause them to start drinking again to feel better, even though doing so can lead to physical or psychological problems. Learn more about alcohol use disorder. |
|
What are the treatments for Alcohol Use and Older Adults ? | There is not one right treatment for everyone with alcohol problems. In general, many people need more than one kind of treatment. Medicines can help people with alcohol use disorder quit drinking. Meeting with a therapist or substance-abuse counselor or with a support group may also help. Support from family and friends is important, too. A doctor can help a person decide on the best treatment. Making a change sooner rather than later makes treatment more likely to succeed.

What are the treatments for Alcohol Use and Older Adults ? | Prescription medicines can help people with alcohol use disorder reduce their drinking, avoid going back to heavy drinking, and get sober. None of them works in every person. There are three medications approved by the U.S. Food and Drug Administration for the treatment of alcohol use disorder. - Naltrexone (Depade, ReVia, Vivitrol) acts in the brain to reduce craving for alcohol - Acamprosate (Campral) helps manage withdrawal symptoms such as anxiety, nausea, and sweating that may lead to a drinking relapse - Disulfiram (Antabuse) makes a person feel sick after drinking alcohol.

Where to find support for people with Alcohol Use and Older Adults ? | Many people with alcohol problems find it helpful to talk with others who have faced similar problems. Mutual help groups, such as Alcoholics Anonymous (AA) 12-step programs, help people recover from alcohol use disorder. AA meetings are open to anyone who wants to stop drinking. Attending mutual-help groups is beneficial for many people who want to stop drinking. Many people continue to go to support/mutual help groups even after medical treatment for their alcohol problems ends. There are other mutual help groups available such as Smart Recovery, Life Ring, and Moderation Management. Learn more about available types of treatment for alcohol problems. |
|
What is (are) Alcohol Use and Older Adults ? | Some people with an alcohol use disorder are treated in a facility, such as a hospital, mental health center, or substance abuse clinic. Treatment may last as long as several weeks. This type of treatment typically involves detoxification (when a person is weaned from alcohol), medicine, and counseling.
