Tamoxifen for Flat Epithelial Atypia?

I'm 52, pre-menopausal.  My open biopsy showed Flat Epithelial Atypia (FEA), and my surgeon is suggesting I see an oncologist for a course of Tamoxifen for 5 years.   He says research shows it decreases the chances of getting cancer by 50% for women with FEA.  Do you agree?  Is FEA hormone receptive?  Should I have genetic testing, as my mother had breast cancer 25 years ago (survived), two great aunts died from it, my grandmother had uterine cancer (survived), and 2 great aunts died from it.  My mom now has bladder cancer, Dad has colon cancer, and had prostate cancer and melanoma.  My brother had testicular cancer (survived).  Whew!

Hi, you asked really good questions I'm curious about this myself.  I'm high risk  for breast cancer and this sounds like something that may be worth looking into. It doesn't hurt to be as informed as possible, I hope you get a response and all goes well.
