Question:  What is (are) Skin Cancer ?
Answer: 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.
Question:  What is (are) Skin Cancer ?
Answer: 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.
Question:  What is (are) Skin Cancer ?
Answer: 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.
Question:  What is (are) Skin Cancer ?
Answer: 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.
Question:  Who is at risk for Skin Cancer? ?
Answer: 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. In 2008 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/.
Question:  Who is at risk for Skin Cancer? ?
Answer: 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. To reduce the video, press the Escape (Esc) button on your keyboard.) Darker-colored clothing is more protective against the sun. A white t-shirt, for example, provides little resistance to ultraviolet (UV) rays, particularly if it gets wet. 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. When going outside, you should always wear sunscreen and lipscreen. Your sunscreen should have an SPF of at least 15. UV radiation can also come from sunlamps, tanning beds, or tanning booths. UV radiation is present even in cold weather or on a cloudy day. A person's risk of cancer is related to lifetime exposure to UV radiation.
Question:  What is (are) Skin Cancer ?
Answer: SPF is a sun protection rating. 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.
Question:  What are the symptoms of Skin Cancer ?
Answer: 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. 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. Other symptoms of skin cancer include a bleeding mole or the appearance of more moles around the first one.
Question:  What is (are) Skin Cancer ?
Answer: 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.
Question:  What are the treatments for Skin Cancer ?
Answer: 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. 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. 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.
Question:  What are the treatments for Skin Cancer ?
Answer: 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. 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.

Question:  What is (are) Gum (Periodontal) Disease ?
Answer: An Infection of the Gums and Surrounding Tissues Gum (periodontal) disease is an infection of the gums and surrounding tissues that hold teeth in place. The two forms of gum disease are gingivitis, a mild form that is reversible with good oral hygiene, and periodontitis, a more severe form that can damage the soft tissues and bone that support teeth. If left untreated, periodontitis can lead to tooth loss. In its early stages, gum disease is usually painless, and many people are not aware that they have it. In more advanced cases, gum disease can cause sore gums and pain when chewing. Not A Normal Part of Aging The good news is that gum disease can be prevented. It does not have to be a part of growing older. With thorough brushing and flossing and regular professional cleanings by your dentist, you can reduce your risk of developing gum disease as you age. If you have been treated for gum disease, sticking to a proper oral hygiene routine and visiting your dentist for regular cleanings can minimize the chances that it will come back. Plaque Buildup Can Form Tartar Gum disease is typically caused by poor brushing and flossing habits that allow dental plaque -- a sticky film of bacteria -- to build up on the teeth. Plaque that is not removed can harden and form tartar that brushing doesn't clean. Only a professional cleaning by a dentist or dental hygienist can remove tartar. Gum disease can range from simple gum inflammation to serious disease. The two forms of gum disease are gingivitis and periodontitis. Gingivitis and Periodontitis In gingivitis, the gums become red, swollen and can bleed easily. Gingivitis can usually be reversed with daily brushing and flossing, and regular cleaning by a dentist or dental hygienist. This form of gum disease does not include any loss of bone and tissue that hold teeth in place. When gingivitis is not treated, it can advance to periodontitis. In periodontitis, gums pull away from the teeth and form spaces (called "pockets") that become infected. The body's immune system fights the bacteria as the plaque spreads and grows below the gum line. Bacterial toxins and the body's natural response to infection start to break down the bone and connective tissue that hold teeth in place. If not treated, the bones, gums, and tissue that support the teeth are destroyed. The teeth may eventually become loose and may have to be removed.
Question:  What are the symptoms of Gum (Periodontal) Disease ?
Answer: Symptoms Symptoms of gum disease may include: - bad breath that won't go away   - red or swollen gums   - tender or bleeding gums  - painful chewing   - loose teeth   - sensitive teeth  - receding gums or longer appearing teeth  bad breath that won't go away red or swollen gums tender or bleeding gums painful chewing loose teeth sensitive teeth receding gums or longer appearing teeth If You Have Symptoms Any of these symptoms may be a sign of a serious problem that should be checked by a dentist. Sometimes gum disease has no clear symptoms. At your dental visit, the dentist or hygienist should - ask about your medical history to identify any conditions or risk factors (such as smoking) that may contribute to gum disease.   - examine your gums and note any signs of inflammation.   - use a tiny ruler called a 'probe' to check for and measure any pockets. In a healthy mouth, the depth of these pockets is usually between 1 and 3 millimeters. This test for pocket depth is usually painless.  ask about your medical history to identify any conditions or risk factors (such as smoking) that may contribute to gum disease. examine your gums and note any signs of inflammation. use a tiny ruler called a 'probe' to check for and measure any pockets.

Question:  What is (are) Gum (Periodontal) Disease ?
Answer: When gingivitis is not treated, it can advance to periodontitis (which means "inflammation around the tooth.") In periodontitis, gums pull away from the teeth and form "pockets" that become infected. The body's immune system fights the bacteria as the plaque spreads and grows below the gum line. Bacterial toxins and the body's enzymes fighting the infection actually start to break down the bone and tissue that hold teeth in place. If not treated, the bones, gums, and tissue that support the teeth are destroyed. The teeth may eventually become loose and have to be removed.
Question:  What are the treatments for Gum (Periodontal) Disease ?
Answer: If left untreated, gum disease can lead to tooth loss. Gum disease is the leading cause of tooth loss in older adults.
Question:  What causes Gum (Periodontal) Disease ?
Answer: In some studies, researchers have observed that people with periodontal disease (when compared to people without periodontal disease) were more likely to develop heart disease or have difficulty controlling their blood sugar. But so far, it has not been determined whether periodontal disease is the cause of these conditions. There may be other reasons people with periodontal disease sometimes develop additional health problems. For example, something else may be causing both the gum disease and the other condition, or it could be a coincidence that gum disease and other health problems are present together. More research is needed to clarify whether gum disease actually causes health problems beyond the mouth, and whether treating gum disease can keep other health conditions from developing. In the meantime, it's a fact that controlling periodontal disease can save your teeth -- a very good reason to take care of your teeth and gums.
Question:  Who is at risk for Gum (Periodontal) Disease? ?
Answer: There are a number of risk factors that can increase your chances of developing periodontal disease. - Smoking is one of the most significant risk factors associated with the development of gum disease and can even lower the chances for successful treatment.  - Hormonal changes in women can make gums more sensitive and make it easier for gingivitis to develop.   - Diabetes puts people at higher risk for developing infections, including gum disease.   - Diseases like cancer or AIDS and their treatments can also affect the health of gums.   - There are hundreds of prescription and over-the-counter medications that can reduce the flow of saliva, which has a protective effect on the mouth. Without enough saliva, the mouth is vulnerable to infections such as gum disease. And some medicines can cause abnormal overgrowth of the gum tissue; this can make it difficult to keep teeth and gums clean.   - Some people are more prone to severe gum disease because of their genetic makeup.

Question:  How to prevent Gum (Periodontal) Disease ?
Answer: Yes, you can prevent gum disease with proper dental hygiene and regular cleanings by your dentist or dental hygienist. Specifically, you should - brush your teeth twice a day (with a fluoride toothpaste).   - floss regularly to remove plaque from between teeth. Or use a device such as a special pick recommended by a dental professional.   - visit the dentist routinely for a check-up and professional cleaning.  - not smoke.  - eat a well-balanced diet.

Question:  What causes Gum (Periodontal) Disease ?
Answer: If your hands have become stiff because of arthritis or if you have a physical disability, you may find it difficult to use your toothbrush or dental floss. The following tips might make it easier for you to clean your teeth and gums. Make the toothbrush easier to hold. The same kind of Velcro strap used to hold food utensils is helpful for some people. Make the toothbrush handle bigger. You can cut a small slit in the side of a tennis ball and slide it onto the handle of the toothbrush. You can also buy a toothbrush with a large handle, or you can slide a bicycle grip onto the handle. Attaching foam tubing, available from home health care catalogs, is also helpful. Try other toothbrush options. A power toothbrush might make brushing easier. Some people may find that it takes time to get used to a power toothbrush. A floss holder can make it easier to hold the dental floss. Also, talk with your dentist about whether an oral irrigation system, special small brushes, or other instruments that clean between teeth are right for you. Be sure to check with your dentist, though, before using any of these methods since they may injure the gums if used improperly.
