A mastectomy may be preferable to lifetime surveillance for women that carry a breast cancer gene mutation, suggest Dutch investigators.
Dr Reinie Kaas, a researcher at the Netherlands Cancer Institute, Amsterdam, told delegates at the European Breast Cancer conference in Berlin this week that prophylactic breast removal left a remaining risk of breast cancer of 1%.
She examined outcomes in 250 carriers of the gene types BRCA1 or 2 that had opted for mastectomy. Only one went on to develop cancer.
Mastectomy saved women the stress of regular checkups as well as saving health service costs, she told delegates.
