All:
Very interesting. I still have a white spot on my tongue.
I had cancer in my tonsil, a radical neck discection and 33 rad treatments.
The white spot showed up a few days after I had braces put on to correct my teeth. They weren't quite put back right after my surgery. My tongue hurt very badly. My oncolgist suggested I go back and have my braces filed down because they seemed to be irritating my tongue. I did. My tongue felt better in a day or two.
The white spot didn't go away. Eventually, I had it biopsied and it was benign.
It's still there. A bit smaller but we are keeping an eye on it.
