Preliminary results of an epidemiological study of skin cancer are presented. Ultraviolet-B (UV-B) exposure was measured in various major metropolitan areas. Data was obtained on skin cancer incidence rates by sex, geographic area, and anatomical site of the cancer. Interview studies also were conducted with skin cancer patients and a general population sample in each location to determine physical characteristics, ancestry or ethnic categories, employment in outdoor occupations, and ability to develop a deep tan. UV-B exposure and the incidence of skin cancer increased as latitude decreased. The incidence of skin cancer for males was about twice that for females in all geographic areas. The increased risk for males appeared as early as age 30 in southern locales but not until about age 45 in northern and central regions. About 80 percent of malignant lesions appeared on exposed areas of the body. Basal cell and squamous cell cancers occurred most frequently on the face, head, and neck. An increase of 1 percent in UV-B levels caused an increase in skin cancer of 1.5 to 2 percent or more. More skin cancer patients had fair complexions, blue eyes, and blonde or red hair than people in the general population. The proportion of persons in outdoor jobs was higher in the patient population than in the general population as was the number of people unable to tan easily.
