Breast MRI's better cancer detection outweighs false-positive 'harm'
May 28, 2020 -- Breast MRI can produce more false positives on initial screening in women at higher cancer risk -- an outcome many consider a "harm" -- but patients and their doctors may decide this is justified by the modality's higher cancer detection rate, according to a study published May 15 in Clinical Imaging.  Discuss
