The only treatment they can do is Chemo and they said it would only buy him a month or so.  What are we looking at on approx. time in general?  no one has said, they just say hes terminal.
[|AI|]  Hi, Thanks for writing in. Sorry to hear about your dad having stage IV throat cancer. The tumor wrapping around the carotid artery is a delicate situation and one of the reasons his treatment options are limited. The main objective when treating a terminal condition is to ad Chat Doctor.  Following pain management, chemotherapy is the next goal and I feel you must go ahead with chemotherapy even if it means he will love a month or two more. Life expectancy in stage 4 cancer can vary anywhere from 6 months to 18 months depending on the involvement of structures around the tumor and spread to other organs. Cancer is a difficult condition to treat and his battle with cancer should be fought till the end. I recommend the chemotherapy if he is able to tolerate the treatment. Please do not worry.
