PALB2 Positive

PALB2 Positive. (F37) Posting here because I can't find any groups specifically for that genre mutation. Considering prophylactic bilateral Mastectomy. My mom died from breast cancer at 56, grandmother from breast cancer at 59, and great grandmother from ovarian cancer at 39. A few other cases of it from the same family line. I'm the first one to have the genetic testing. I almost feel relieved like, I've named the demon, and now we can do an exorcism. Anyone else have experience with PALB2?
