Study: False positives have high rate of cancer later

Women who have received false positive mammograms, meaning the results suggested breast cancer, had a 67% higher rate of developing breast cancer later.

Authors of a study in the Journal of the National Cancer Institute say the false positive test may be attributable to misclassification of malignancies already present at the baseline assessment or to a biological susceptibility.

Authors say this study suggests women who have false positives should be monitored closely over time.
