Breast reduction surgery and breast cancer risk: Does reduction mammaplasty have a role in primary prevention strategies for women at high risk of breast cancer?

to reduce breast cancer incidence in women with a high inherited susceptibility to breast cancer. For the majority of high-risk women, however, bilateral prophylactic mastectomy is not an acceptable option for primary prevention of breast cancer. Several epidemiological follow-up Studies have indicated that there may be a substantial reduction in breast. cancer risk among women who have undergone breast reduction surgery. The authors, reviewed the evidence from these studies, with emphasis on the problems inherent in interpreting the results of nonexperimental studies of elective medical procedures. Although Such observational studies cannot demonstrate definitively that reduction mammaplasty reduces the risk of breast cancer, the evidence from these studies is sufficiently strong to warrant the evaluation of breast reduction surgery as an option for primary prevention in clinical Studies of women at increased risk of breast cancer. The availability, of a more acceptable surgical option for primary prevention of breast cancer could increase the number of women willing to choose risk reduction surgery and thus may result in an overall reduction in breast cancer mortality among high-risk women.
