Hi Dotti. I believe the FISH is used to test for the HER2 protein and a common tx for that is Herceptin. Tamoxafin is a tx for estrogen and/or progesterone.
My lab results showed the tumor I had a 4% progesterone+ however we have not treated that way yet.
I advise you discuss your concerns w/your ONC since you do have a good relationship. Let us know how it goes!
