A study co-led by Professor Kelly Metcalfe of the Lawrence Bloomberg Faculty of Nursing, and researchers at the Familial Breast Cancer Research Unit at Women’s College Hospital, finds risk-reducing mastectomies (RRM) in women with a BRCA1 or BRCA2 genetic variant, significantly reduces the risk of being diagnosed with breast cancer and lowers the probability of death.
