There's solid evidence that basal and squamous cell cancers, which account for 90% of skin cancers, are directly linked to cumulative UV exposure, cancer experts say. Basal cell cancers mostly occur on the face and have a very small risk of spreading. Squamous cell, which occur on the ears, lips, temples, can spread and cause about 1,200 deaths per year. The relationship between UV exposure and melanoma is less clear, since some melanomas occur in parts of the body that rarely get sun. Experts say about 65% of cases are UV-related. Recent studies of the melanoma genome have found that most mutations—changes or errors in the genes that lead to cancer—were caused by UV radiation.
