[|AI|]  Hi, dairy have gone through your question. I can understand your concern.  He has widespread metastatic carcinoma.  So it is stage 4 of prostate cancer. Surgery will not helpful.  Treatment options are chemotherapy and radiotherapy. Despite treatment prognosis remains very poor.  Life expectancy is not good.  ONR should not expect much front his case.  Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
