Skin cancer is the most common type of cancer in the United States. Most cases are caused by excessive exposure to ultraviolet (UV) rays from the sun, tanning beds, or sunlamps, because skin cells begin to multiply uncontrollably. The two main layers in the skin are the epidermis or upper/outer layer and the dermis or lower/inner layer. Skin cancer begins in the epidermis, made up of squamous cells, basal cells and melanocytes. Melanin is the pigment that gives color to the skin, when the skin is exposed to the sun, the melanocytes produce more pigment and cause the skin to darken. Melanoma is the third most common type of skin cancer and causes the most deaths, due to its tendency to spread to other parts of the body, including vital organs, and begins in melanocytes.
