My uncle recently went through this. It all depends on how far along
the cancer is. His doctor caught the cancer very early on & I'm very
happy to say that he is doing fine. He had surgery, the infected area
was removed, and had 6 months of out-patient chemo, I belive. He
is now cancer free, and no worse for the wear, so far as I can see.
I am not with him everyday so I can't say "for sure" how his life
has been affected by this. But he is healthy & cancer free. Hope
that helps M2!
