Welcome to OCF! So sorry to hear about your fathers recurrence.

Its pretty difficult to try giving any type of prognosis over the internet. The best thing I can tell you is to find the very best medical professionals available and then finding some at a different cancer center for a second opinion.

The treatments to eliminate cancer are either surgery or radiation with or without chemo. If surgery and radiation are out of the question than sadly your father wont be curable. Chemo can be given as a palliative measure to help shrink the tumor and extend his life. But chemo alone will not cure his cancer. Some 'old school' medical professionals will say radiation is only a one time option. But there are several members here who have had it more than once. This is a very individual thing and varies on a case by case basis. If your father hasnt had radiation then I would suggest asking. Even if he has had it ask if a second round is possible.

Best wishes with everything!!!
