New research shows that while bilateral mastectomy lowers the risk of cancer in the opposite breast, it doesn’t improve overall survival rates. This finding may influence decisions for women with unilateral breast cancer, challenging the notion that more aggressive surgery yields better long-term outcomes.

They aimed to determine if bilateral mastectomy (removal of both breasts) offers a survival advantage over lumpectomy (removal of tumor and small surrounding area) or unilateral mastectomy (removal of one breast)....
