A recent U.S. Preventive Services Task Force report suggests that while mammograms save lives, they also lead to unnecessary additional procedures. Experts suggest that the problem with mammography is that improvements are needed to reduce false positives and increase accuracy. As mammography has advanced from film-based imaging to digital imaging, the digital images provide greater levels of detail, revealing areas of interest that previously weren't visible -- and containing far more information than the human eye can possibly see or interpret.
