I was diagnosed with stage 4 prostate cancer 5 months ago. its in the bones lymph nodes and maybe some organs. Doing great with prednisone, zytiga and Lupron (chemo). I'm strong, active and have very little fatigue. Seen my doctor last week and he really can't give me a window of how long I have. He just said that when mine was found, it was very advanced. He was so happy with my bloodwork, my red cell count in the 12's. Can anyone give me a window of how long I have. I'm 66 and trying to get things in order for my wife. My psa is below 1 at the moment.
