[|AI|]  Hi, dairy have gone through your question. I can understand your concern. He has lung cancer of stage 4. It is not curable.  Radiotherapy and chemotherapy are useful for palliative treatment. Despite all treatment prognosis remains poor.  Life expectancy is not good.  One should not expect much from this case.  Sorry to say but it is fact. Consult your doctor and plan 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.
