Skin cancers develop most commonly on sun-exposed skin including the backs of the hands and arms, upper trunk, face, nose, lips, ears, lower legs, and the hairless scalp. They much less commonly involve the nail bed, bottom of the feet, and the genital areas. Skin cancers are most common in people with lighter skin tones. There are three common skin cancers -- basal cell carcinoma, squamous cell carcinoma, and melanoma. Actinic keratoses are referred to as "pre-cancers."
