Mammograms do not cut risk of dying in over-75s

Women aged 75 and older do not benefit from regular screening mammograms, a US study finds, offering some of the first evidence on whether screening makes sense in these women.

Elderly patient getting a mammogram

US researchers used claims from the federal Medicare insurance program for the elderly, looking at data on more than one million women aged 70-84, who underwent mammograms from 2000-08.

Women in the study had a life expectancy of at least 10 years and no prior breast cancer diagnosis.
