Have you heard of Pink Hope?
www.pinkhope.org.au ;
This organisation is for people with high risk of breast/ovarian cancer. Mostly BRCA positive ladies. You might find some answers there.
I know a few ladies with BRCA2 in my support group for young women in facebook land lol... if your interested let me know and i can send you an invite to join that group.
Well done at nearly finishing Chemo... Not long now! I think having a double mastectomy is a smart move for you. Do you know what Recon you will have?
