Mammogram Every 2 Years May Be OK for Older Women
The society's current guidelines recommend annual mammograms for women age 40 and over, as long as they are in good health. Age alone should not be a reason to stop having the screening, according to the guidelines, but women with short life expectancies or serious health problems should discuss the pros and cons of screening with their doctor, the society suggests.
Decisions about guidelines are constantly evolving, Lichtenfeld said, as more research is published.
Judith Malmgren, an affiliate assistant professor of epidemiology at the University of Washington, in Seattle, said the new study "confirms earlier studies that biennial screening is fine for older women with fewer false-positives."
However, she said, women with a family history or those who feel uncomfortable with the longer interval should opt for annual exams.
The study was funded by a variety of grants from the U.S. National Cancer Institute and others. Braithwaite was partially funded by the Mentored Research Scholar Award from the American Cancer Society.
