Is this drug a chemo therapy? My dad has advance PC that's spread to his bones, nothing in his vital organs,yet. His most recent PSA is now at 1000.His oncologist has stopped hormone therapy recommending chemo/radiation and pallative care/hospice. Chemo at his age (75) and in his condition ( very weak and lost an alarming amount of weight/wasting) we believe will kill him and besides,he's suffering enough.I don't want to give up hope,but it looks to us (the family) that he is going to pass soon. At this point he is just existing trying to manage the pain. I HATE this disease!!! Cindy
