Study: Breast cancer tests 'frequently misinterpreted'

CHICAGO (WLS) -- Tests for breast cancer are frequently misinterpreted, according to new findings published Tuesday in the Journal of the American Medical Association.

The study asked more than 100 specialists to diagnose breast tissue biopsies, and then compared their answers with the opinions of three experts. When the specimens were abnormal, the specialists made a wrong diagnosis about half the time.

That means some patients' cancer might go undetected, while others may get unnecessary treatment.

Some are critical of the study's results, saying in the real world, doctors consult with colleagues before making a diagnosis.
