UCSF Study: Older Women Should Get Mammograms Every Two Years

Listen to the audio:

How often women in their 40s and 50s should get mammograms has been a hot research topic for a couple of decades -- and it remains the subject of intense debate. But what about mammograms for older women? Far less research has been done on this population.

Host Stephanie Martin talks with KQED Health Editor Lisa Aliferis about a major national study published Tuesday by researchers at UCSF.

The study concludes that women aged 66 to 89 should receive a mammogram every two years, instead of one. Researchers found that women who were screened every two years were not at a higher risk for cancer -- and that more frequent screenings result in dramatically higher risk of false positives, leading to unnecessary biopsies.
