Susan, I know what your husband is going through. I had a hemiglossectomy on May 17 2018 to remove 60% of my tongue and the lymph nodes in my neck. I had good clear margins. About three weeks ago, I stared having pain in my tongue that got worse over time. The doctors told me I was biting it but I can't bite the bottom of my tongue back farther than my teeth are. About a week and a half ago I started radiation. The pain on my tongue got so bad I couldn't wear the teeth guards and could hardly eat. I convinced them to do a CT scan. It showed a tumor on my tongue almost an inch by an inch in size. A biopsy showed it was cancer. It was growing while I was having radiation and is even into the new part of my tongue. I discussed additional surgery but the surgeon said he wouldn't suggest it. After hearing what my quality of life would be, I agree with him. My only option is chemo and radiation and the chances of it working are slim. If they can't shrink it my surgeon said I have about two months left. Sorry I can't give you any words of encouragement but know that he isn't the only one this has happened to. I hope he has a good outcome.
