Mathematical Models of Age and Ultraviolet Effects on the Incidence of Skin Cancer Among Whites in the United States

That sunlight leads to skin cancer has been generally accepted for nearly a century. Physical data are, for the first time, available which support this hypothesis. The authors have found that a simple power relationship can be used to describe the data and that the form of this power function suggests that the risk of nonmelanoma skin cancer is related to cumulative lifetime ultraviolet (UV) exposure and that the risk of melanoma skin cancer is related to annual UV exposure. The authors emphasize that skin cancer risk also depends on location-specific demographic variables other than ultraviolet radiation.
