Mammograms May Have Hidden Risks
A new study looks at how often women in their 40's should get mammograms if they have double the average risk of getting breast cancer.
Researchers at Georgetown University found the benefits of getting the screening every other year outweigh the potential harms, but yearly mammograms may do more bad than good.
That's because the high rate of false positive test results sometimes lead to needless procedures, pain and anxiety.
The study also found that digital mammograms had substantially more false-positive results than film mammograms.
