<s>[INST] my close friends husband has liver cancer, colon cancer,kidney stones & now his spleen is very enlarged and the doctors have sent him home to die and my friend hasnt been told as what to expect,time wise etc. and has asked me to see what I can find out for her. She just wants to be on top of things and cant quite get the answers from their doctor. Can you tell me anything that will help her she has taken care of him for so long and is trying to keep on top of things but is getting very worried as hes in a lot of pain and his stomach is very swollen and cant eat very much. Hes on very strong pain meds. [/INST] Hi, dairy have gone through your question. I can understand your concern. He has colon cancer with liver metastasis. It is stage 4 cancer. 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. So according to my opinion no any treatment should be given for cancer. For renal stone analgesic can be given. Morphine or other morphine based painkiller can be given to relieve pain. It is indicated in terminal stage cancer pain. It is prescription based medicine so consult your doctor and take treatment 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. </s>
