Sherrie,
Your husband's cancer sounds almost just like my husbands. He had a tumor in the very center of his tonsil, was not visible, and it had spread to three lymph nodes. They said his was his tonsillar fossa, though. We went to MD Anderson and after meeting with the board, they decided not to do chemo, just radiation to both sides. I don't know why some do it and some don't. I think I might have felt a little better if they had done chemo, of course I would probably still get the nerves that come every time we go back for a checkup.
