Abstract

For the 10-year period 1965 through 1974 the age-specific death rates for cancer of the breast decreased among middle-aged women, especially at ages 40 to 49 years, in Quebec, the Maritimes and the Prairies but not in Ontario or British Columbia. In women under 35 years of age the mortality generally increased, while in women aged 60 to 64 years there was little change except in the Prairies, where the rate increased. It seems probable that the trends reflect changes in incidence rather than in case-fatality. Some, but not all, of the pattern could be explained by changes in fertility over the past 50 years.
