Ways to Avoid False-Positive Screening Mammograms
August 1st 1999NEW ORLEANS-Steps can be taken to reduce the number of false-positive results with screening mammography, W. Phil Evans, MD, said at the American Society of Breast Disease annual meeting. “But false positives may not be such a catastrophe.
