Mammography does not reduce breast cancer deaths in women 75 and older

Key clinical point: In women aged 75 years and older, annual mammography did not reduce breast cancer deaths when compared with no screening.

Major finding: Among women aged 75-84 years, the estimated 8-year risk for breast cancer death was 3.8 deaths per 1,000 women for patients who had annual screening mammography and 3.7 deaths per 1,000 women for patients who stopped screening.

Study details: An observational study looking at records for more than 1 million women on Medicare during 2000-2008.

Disclosures: The National Institutes of Health sponsored the study. One coauthor declared industry support.
