Skin cancer is a cancer of the cells in the outermost layer of skin, called the epidermis.

What Causes Skin Cancer?
Besides lung cancer, skin cancer is one of the most preventable types of cancer. This is due to the fact that the major risk factor is ultraviolet (UV) radiation. The sun is, of course, the main source of UV radiation, but it can also come from tanning booths. The amount of UV exposure depends on the strength of the light, how long the skin was exposed, and whether the skin was covered with clothing or sunscreen. Many studies also show that being sunburned at a young age increases the likelihood of skin cancer even decades later.
