Welcome to the Oral Cancer Foundation jc.

It's very normal to be scared about this diaease. We all are at the point he is at. I was a stage 4, right tonsil also. Going thru treatment is no picnic but many of of have and survived. I see no reason why he can't to.

If you go to the search engine at the top of the page you can read many postings about treatment and it's side effects. The more knowledge you have the better questions you will have to make sound decisions about his treatment.

Like Mark says many of us went thru without getting our teeth pulled. Has he had a second opinion on his condition? Is he being treated at a Comprensive Cancer Center?
You want someone who sees alot of what he has treating him. A team of disiplines that come to a mutual decision on how best to treat him. Again welcome and let us know how he's doing.

All my best, Danny Boy
