Skin cancer is the most common form of cancer in the United States. Although skin cancer is not tracked by most cancer registries, the American Cancer Society estimates that more than five million skin cancer cases are diagnosed in the US every year. These are usually divided into three types: squamous cell carcinoma, basal cell carcinoma, and melanoma.
For all of these types of skin cancer, the main symptom is a growth or mole on the skin. The growth can appear virtually anywhere on the body.
Most basal cell carcinomas are shiny, pale growths that may be raised or flat. Squamous cell carcinomas are usually raised and crusty. Melanoma growths appear as a difference in an existing mole, such as a change in color, border, shape, or size. Sores that do not heal and skin lesions are also common signs of skin cancer.
