The Age-adjusted Death Rates for Malignant Neoplasms in Some Selected Sites in 23 Countries in 1954-1955 and their Geographical Correlation

Basing ourselves on the population and mortality statistics furnished us by the central statistical administrations of 23 countries, we computed the age-adjusted death rates for cancers of all sites, the esophagus, the stomach, the intestine, the rectum, the pancreas, the lung, the breast, the uterus, the ovary and the prostate and of leukemia and aleukemia in these countries in the years 1954-55, taking the sum of the male and female populations by five-year age-classes of 46 countries around 1950 as standard, for examining the status of cancer mortality in these countries. The items surveyed comprise comparisons of the adjusted death-rates by countries and by sites, comparison of the sex ratios of the death rates by sites and by countries, the geographical correlation of male and female death rates by sites and the geographical correlation of male and female death rates of cancers of the same sites.
