I don't know if they froze the sample they removed in Dec. or not.... I just know that it was benign. I was just telling someone else that even though they removed a good sized sample (1" x 1/2" deep). maybe they didn't remove a large enough one.
The problem I have is also on the far back right side of my tongue. A lot of times it's hard for me to get a good look at it.
I was sorry to hear that you are getting ready to undergo treatment. I hope everything goes okay with that, and that you start feeling better soon!
