Epidemiological study reveals static age-adjusted breast cancer mortality rates in United States populations, suggesting a contradiction with reported survival gains.
H to mammary cancer been essentially static for the past 30 years? Consider available mortality data for the United States (Fig. When adjustment is made for the aging of the population, there is seen to be little change between 1930 and 1960 in the mammary cancer mortality rate. This constant mortality rate, when taken together with numerous reports across the nation of improvement in survival rates, seems to be paradoxical.
