Researchers found those who interpret a higher number of mammograms every year have fewer false-positives for their patients.
The study did find that radiologists with both low and high mammogram workloads were equally good at catching breast cancer. However, those who looked at fewer mammograms had more false alarms.
Radiologists in the U.S. are required to review at least 960 mammograms every two years. Researchers recommend that number be increased to 1,000 or 1,500.
