Age dependence of cohort phenomena in breast cancer mortality in the United States.
Breast cancer mortality has increased in most parts of the world, and many explanations have been postulated. In this paper, the authors examined the evolution of mortality rates for white and nonwhite females in the United States from 1950-1979. Using both graphic techniques and Poisson regression models, they found that there has been strong modification of apparent cohort effects by age. For both white and nonwhite females, they observed an increase in mortality rates limited to the postmenopausal ages.
