Hi, Debo
I am going to respectfully disagree with Don in that I would NOT ask about prognosis. I would ask about what chemo agent(s) they are using, and what the schedule is for the chemo and radiation. That will give us a clue about when he will feel the worst, and maybe need some extra help. You could also ask about staging, but you may have to be careful asking about this, too.
Best wishes -
Maria
