INFLUENCE OF AGE, YEAR OF BIRTH, AND DATE ON MORTALITY FROM MALIGNANT-MELANOMA IN THE POPULATIONS OF ENGLAND AND WALES, CANADA, AND THE WHITE-POPULATION OF THE UNITED-STATES

The age-adjusted death rates from malignant melanoma of the skin have increased from 1951 to 1975 by about 3% per year in the populations of England and Wales, Canada, and the white population of the US. This is due to large increases in risk of successively later born cohorts. Any effects of earlier diagnosis of improved treatment within the period 1951-1975 have been sufficiently steady to fail to alter these trends. The slope of the log rates with log age is about 3.5. Projections of rates for at least the next decade can be made with some confidence, and provide a basis for evaluating control measures. © 1979 by The Johns Hopkins University School of Hygiene and Public Health.
