The purpose of this study was to determine the crude and age-adjusted incidence rates of melanoma for residents of Puerto Rico from 1975 to 1991. This is part of an ongoing NASA study aimed at estimating whether melanoma and cataracts have increased in Puerto Rico since 1978 because of potential stratospheric ozone depletion and increased ultraviolet-B (UV-B) radiation. Calculating the percent change from their lowest values in 1978 to 1991, the age-adjusted incidence rate of melanoma increased 528% for males and 200% for females in 13 years.
