Trends of female mortality from cancer of the breast and cancer of the genital organs.

The author reviews the mortality statistics from cancer of the breast in females and from malignant neoplasms of the uterus and of the other female genital organs for nineteen countries over the years 1920-53, first considering the general trend of the mortality series for each group of diseases for all ages and then analysing for each sector of mortality the changes which have occurred in the age-specific deathrates in some pivotal years during the same period.Considerable differences in the levels of total mortality from each group of tumours for various countries are noted. The important variations among age-specific death-rates for cancer of the breast in females and for uterine neoplasms in various countries are examined and their significance is commented upon.
