Increasingly women at high risk of breast cancer are opting for prophylacti
c surgery to reduce their risks. Data from 10 European centres that offer a
risk counselling and screening service to women at risk show different app
roaches to the option of preventive surgery, although most centres adhere t
o a protocol including at least two risk counselling sessions and a psychol
ogical assessment. Thus far the combined centres have data on 174 women who
have undergone prophylactic mastectomy with in excess of 400 women years o
f follow up. Operations were carried out on women with lifetime risks of 25
-80%, with an average annual expected incidence rate of 1% per women. No br
east cancers have occurred in this cohort. Long term follow up on an extend
ed group of women will be necessary to truly address the risk of subsequent
breast cancer and the psychological sequelae.
