Melanoma is a type of cancer that starts in pigment-producing cells called melanocytes. Usually melanoma starts in the skin, but in some cases, there are no visible external signs of the disease. It also can begin in pigment cells in the eye or in mucous membranes in the mouth, sinuses, anus, vagina or other areas.
