Are Screening Mammographies Reducing The Rate Of Death From Breast Cancer?

An article last week in the New England Journal of Medicine explores the effect of three decades of screening mammography on breast cancer incidence.  The conclusion from the article states:
“Despite substantial increases in the number of cases of early-stage breast cancer detected, screening mammography has only marginally reduced the rate at which women present with advanced cancer. Although it is not certain which women have been affected, the imbalance suggests that there is substantial overdiagnosis, accounting for nearly a third of all newly diagnosed breast cancers, and that screening is having, at best, only a small effect on the rate of death from breast cancer.”
