Would you recommend prophylactic mastectomy if a patient's estimated lifetime risk of breast cancer using the Gail or Clause models approaches that of a person with a germline BRCA1 mutation (eg >65-85%), in the absence of high risk mutations?  

Example patient: 50 year old pre-menopausal woman with a familiy history of pre-menopausal BRCA1 and BRCA2 wild-type breast cancers in sister and mother and a personal history of breast biopsies with an estimated lifetime risk for breast cancer is >50%.
