I'm asking for a close family friend. He had locally advanced prostate cancer diagnosis a year and two months ago. A bone scan showed nothing there, but he had one lymph node tumour. He has had hormone treatment and radiotherapy. His last blood test showed his PSA was only 3.8. However, in recent weeks he has gone down hill rapidly. He has almost constant lower back and hip pain and now rib tenderness. He had night sweats last night and we are all very concerned. My query really is, would it really be possible for it to have spread to bones in such a short amount of time and would his PSA be that low? I feel like no matter what he says to the GP, he is fobbed off and despite speaking to 111 today and being sent to a walk in centre, he's been sent back home with basic pain relief. His oncologist is also not really doing anything in any hurry.
