According to a recent study, in almost 16% of the cases, radiologists will report false-positive cancer readings in mammogram x-rays. Many of these radiologists are younger and newly trained doctors who may be likely to make more errors in interpretation than their more experienced counterparts.
The Journal of the National Cancer Institute found that only if the radiologists could compare films from their earlier mammogram screenings, the rate of these “false-positives” could be lowered significantly.
Dr. Joann Elmore, professor of epidemiology at the University of Washington (School of Medicine), says that it is alarming how common false-positives have become in the US. She also said that false-positives are most likely to occur in the case of breast cancer mammogram screenings but it shouldn’t discourage women from having annual check-ups.
