[|AI|]  Hi, dairy have gone through your question. I can understand your concern. He has cancer.  It is stage 4 cancer. Treatment depends on type and stage of cancer. But in general protocol surgery is not useful in this stage. So treatment options are chemotherapy and radiotherapy. But it will not cure the disease. It just works as palliative therapy. Despite all treatment prognosis remains poor. Life expectancy is not good. Sorry to say but it is fact. Consult your oncologist and plan accordingly. Hope I have answered your question, if you have any doubts then contact me at bit.ly/ Chat Doctor. Thanks for using Chat Doctor. Wish you a very good health.
