摘要
Purpose BRCA1 mutation carriers are at high risk for breast cancer (BC). The risk management strategy may include radiological investigations for early detection or prophylactic mastectomy (PM). For a mutation carrier, PM may be more significant than surveillance alone when pre-malignant and malignant changes occur increasingly in mastectomy specimens, given normal findings on radiological investigations. In the present study we retrospectively investigated the differences between histological findings in PM specimens of BRCA1 carriers and those of a control group.
