Double Mastectomies Don’t Yield Expected Results
More women are choosing to have bilateral mastectomies when they are diagnosed with early-stage breast cancer, even though there’s little evidence that removing both breasts improves their survival compared with more conservative treatments.
The biggest study yet on the question has found no survival benefit with bilateral mastectomy compared with breast-conserving surgery with radiation.
