Definition
By Mayo Clinic staffSkin cancer — the abnormal growth of skin cells — most often develops on skin exposed to the sun. But this common form of cancer can also occur on areas of your skin not ordinarily exposed to sunlight.
There are three major types of skin cancer — basal cell carcinoma, squamous cell carcinoma and melanoma, which is the most serious of skin cancer.
All three types of skin cancer are on the rise — but most skin cancers can be prevented by limiting or avoiding exposure to ultraviolet (UV) radiation and by paying attention to suspicious changes in your skin. And with early detection, you can receive successful treatment for most skin cancers, even the most aggressive forms.
