BRAC1 mutation > double mastectomy ?!

Anonymous

My sister is triple negative and has the BRCA1 mutation. She found about the mutation in March. She recently finished chemotherapy.

Prior to chemo she had two lumpectomies in her right breast so far and is scheduled for a third lumpectomy near the end of June. Then 3-6 weeks of radiation.

When she saw her surgeon today, all of a sudden she's recommending a double mastectomy instead of the third lumpectomy. She says with the BRCA1 mutation, my sister has a "5% chance of cancer recurrence." The doctor hadn't discussed this previously (other than telling my sister she had the mutation).

My sister doesn't want a double mastectomy at age 70 because it's major surgery.

Your thoughts PLEASE!

Thank you!
