[|Human|] My father-in=law has beeb suffering from prostrate acncer for 10 years and up until late last year it was controlled. Now it has been discovered that the cancer has spread to his spine in several places. He has already undergone radiotherapy on two occasions but still suffers with acute pain in his back and now down his legs and around his ribcage. He was told yesterday that his spine is crumbling and an operation is not possible. I am looking for answers to the consequences as I feel he does not ask the appropriate questions when he is with the surgeon/consultant. This could be because he does not wish to know but as a close relation I want to know.
[|AI|]  Hello dear. Your father is suffering from stage 4 prostate cancer. At this stage surgery cannot be done for prostate. However, he requires either surgical removal of testes or medical management for inactivation of testosterone produced by the testes. Then he will be requiring chemotherapy and hormonal therapy as a part of treatment. He also requires bone strengthening agents 9 bisphosphonates) Hope that solves your query.
