[|AI|]  Hi, dairy have gone through your question. I can understand your concern. He has prostate cancer stage 4. Blood in urine may be due to cancer spread to bladder or urogenital tract.  Back pain may be due to spread of prostate cancer to spine. It is stage 4 cancer, so surgical treatment is not helpful.  Treatment options are chemotherapy and radiotherapy. Despite treatment prognosis remains poor. 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.
