Lashof, an author of the report, said at a press briefing on breast cancer sponsored by the National Academies.
Clinical trials have shown that mammographic screening reduces breast cancer mortality rates by 25%-30% for women aged 50-70 and 16%-18% for women aged 40-49, according to the 227-page report.
Still, problems with the technology remain. It doesn't detect all cancers, including some that are palpable, and as many as 75% of all lesions that are seen on mammograms and biopsied turn out to be benign.
