Sanantaria,

Welcome to the site. I'm sure there are many people that would hop in and give you information, but you really would have to supply more information to us. If he does have oral cancer - things should be moving pretty fast for him and his treatment. If you can find out more from him it would be helpful.
Until then you might want to go to the sitemap on this site and do some reading - it also has a section on staging, treatments, and variuos information not found anywhere else.

Good luck,
Dinah
