American doctors are continuing to tell women in their early 40’s to get mammograms despite guidelines advising otherwise.

A study out of Johns Hopkins University surveyed about 870 physicians in family medicine, internal medicine and gynecology and found that four out of five doctors recommend women aged 40 to 44 get screened for breast cancer.

But the U.S. Preventative Services guidelines recommendations say women of average baseline risk should start undergoing mammograms at age 50 and then every other year after that. (The guidelines are the same in Canada.)

The findings suggest that physicians are taking a more cautious approach to breast cancer detection, despite differing recommendations by medical societies.
