60 yrs old, biopsy-extensive ALH with ductal involement, prolific fibrocystic breast disease, papilloma in both breasts resulting in total ductectomies. Some CAD, cardiologist review of echo and baseline bone density ok to proceed. Total chol 207, ldl 139, hdl 35, triglycerides 155, A1c 5.3. If side effects of chemo with exemestane suggested for five years are too harsh and interventions to provide relief fail, is bilateral prophalctic mastectomy an option that should be strongly considered? (My mother had bc at 58 had both breasts removed 24 years ago, her paternal grandmother had bc and survived as well as my only paternal aunt.)
