Hi, 
My dad was diagnosed with metastatic prostate cancer last August and was offered hormone therapy as it had spread everywhere and it was about "control not cure". He had been great until December - he's retired and was playing golf a few times a week but then was admitted into hospital over Xmas with spinal cord compression. Since then he has been in a lot of pain, is on morphine and has limited mobility in his left hand. He's still mobile but his appetite has gone after finishing course of steroids. We had a meeting on tues with his oncologist who advised his PSA had risen and that meant the hormone treatments were not working anymore. He offered chemo but my dad said he doesn't want to be sick and not see his grandkids for fear of infections etc. They then offered abiraterone zytiga and my question is, have any of you used this and what were the side effects like? And most importantly, did it work? 
Thanks
Bee
