How to recognize skin cancer and who's most at risk Skin cancer is the uncontrollable growth of abnormal cells in a layer of the skin. Unfortunately, about one out of every seven Americans are afflicted each year, making it the most prevalent form of cancer. However, ninety percent of all skin cancers can be cured if detected and treated in time. According to some estimates, Americans who live to the age of 65 have a risk up to 50 percent of developing skin cancer at least once.
Skin cancer can look many different ways.
The most common sign of skin cancer is a change on the skin, such as a growth or a sore that won't heal. Sometime there may be a small lump. This lump can be smooth, shiny and waxy looking, or it can be red or reddish brown. Skin cancer may also appear as a flat red spot that is rough or scaly. You should see your doctor if you notice changes in your skin.
