Nonmelanoma skin cancer (NMSC)1and melanoma2 are epidemic in the United States. One analysis of a large prepaid health insurance program indicated that the incidence of squamous cell carcinoma (SCC) increased by 2.6 times in men and 3.1 times in women over a 20-year period from the 1960s to the 1980s.3 Another large study put the increase in SCC from 1980 to 1994 at 235% in men and 350% in women and the increase in basal cell skin cancer (BCC) at more than 80% in both sexes.4
