International health insurance customers might want to enquire with their doctor as to how much practice he or she has had at interpreting mammograms.
According to a recent study, published in the journal Radiology, radiologists who interpret more mammograms and spend more time reading diagnostic mammograms tend to be more apt at determining which suspicious breast lesions are cancer.
Study leader Diana Buist, a senior investigator at Group Health Research Institute, explained that it is important to reduce the rate of false-positive diagnoses because these can bring women undue anxiety and also increase healthcare costs.
She added: "We found that radiologists who interpreted more mammograms a year had clinically and statistically significantly fewer false-positive findings – without missing more cancers."
Mammograms are recommended for older women, who are at a greater risk of developing breast cancer.
They involve taking an X-ray of the breast and tend to be used among patients who have symptoms of breast cancer, such as a lump.
