Fellow members @corinneberg @ladylawdawg @elsie37 @doyoga and @casualobserver may be able to share their experiences about prophylactic mastectomy with you. You may also be interested in these discussions:

– High Risk Mutation (ie. BRCA, ATM, RAD51D) https://connect.mayoclinic.org/discussion/high-risk-mutation-ie-brca-atm-rad51d/
- High risk, NOT from BRCA but from typia, such as ALH, ADH, LCIS https://connect.mayoclinic.org/discussion/high-risk-not-from-brca-but-from-typia-such-as-alh-adh-lcis/

I'm glad you started a discussion specific to choosing whether or not to have a preventative double mastectomy (prophylactic bilateral mastectomy). Have you already had surgery or are you currently considering it?
