My cancer started with my tongue as well, as you can see in my profile.  Yes, it is frightening, but mine was stage IV and I am still here after 21/2 years.  Of course, I worry about recurrance, too.  But I try not to get too depressed about it, even though sometimes it's hard not to be.  My husband and I were in an accident this summer-our car got hit by a fire truck, and we also made it through that.  I still have issues with eating, but I am happy to be alive and was blessed last spring to meet my first grandchild.  Life is very precious, and I am more aware of that every day.  Good luck to you.  We are all here for you.
