Thanks for the information. I just have read so many posts regarding doctors missing a diagnosis and even with biopsies missing it that I think I do have oral cancerphobia already. That base of the tongue growth started this paranoia and I cant seem to get past it due to these constant new bumps and ulcers that keep coming up. I'll try to quit worrying. Just one more question..has anyone heard of cancer being so deep inside the tongue that biopsies dont show it?
