<s>[INST] My 61 year old father has been diagnosed with Advanced Level IV Prostate Cancer. He has been healthy in the past beyond arthritic knees. His PSA score was 60 the first test; the 2nd test was 4 (before any treatment). He did not tell me of his condition until 5 months after his diagnosis, and because of this, I am afraid to ask him straight-forward questions. His cancer has spread to the lymph nodes and there is evidence of bone metastases. I dont know how scared I should be. Does he has months or years to live? He is currently taking hormone therapy. [/INST] Hi, dairy have gone through your question. I can understand your concern. He has prostate cancer stage 4 with bone and lymph node metastasis.  Surgery is not helpful In stage 4 cancer.  Chemotherapy, radiation treatment and hormone therapy should be given. Despite treatment prognosis remains poor. Life expectancy is not good. Sorry to say but it is fact. Consult your doctor and take treatment accordingly. 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. </s>
