Skin Cancer, which is becoming more and more common often begins in a mole. A change in the size, shape, color, or thickness of a skin blemish or mole may be an indication of skin cancer. Symptoms of itching, burning, and especially bleeding can indicate a problem. Some people are born with a noticeable significant skin lesion birth mark, mole, or hemangioma, but most often these and other blemishes develop slowly over time. Most of these are harmless. However, over the years irritated skin and moles can turn into cancer. You should be especially careful if you have a family history of skin cancer or if you have moles that have changed in size or appearance.
 
You can reduce the risk of developing skin cancer by avoiding excessive exposure to the sun and other forms of radiation, and by avoiding tobacco use, both smoking and chewing. However, even some people who have a dark complexion, who avoid the sun, and who have never smoked still have problems.
 
The most important thing to remember about skin cancers is that they are almost always curable when detected early. Therefore it is important to have skin cancer screens regularly.
