My Grandad has metastatic advanced prostate cancer and his hormone treatment has stopped working after only 3 mths. His PSA is over 700 and we are waiting for a clinic appointment with oncology to see if there is a treatment available for him.. his appointment is early January but the past few weeks he is deteriorating every day, he has no appetite and can barely drink one Ensure shake per day. He can take fluids. He has a lot of excess saliva and mucus and is easily made feel nauseous. He is weak as a kitten and is now completely bedridden. We have pleaded with him to allow us to call an ambulance so he can get his treatment sooner but he isn't having any of it as he hates hospital so much. We are completely at a loss its so distressing.. is there any coming back from this? He is skin and bone. And it is also beginning to him to pee which will be a real cause for concern soon..
