Get it checked. My little sore on my tongue grew between visit and surgery, it had to come out just because it would not heal, and sure enough a tumir was lurking beneath. It could have gone either way. The rest of my treatment has been preemptive, so don't let it scare you. This is a great place for information, but only the docs can actually tell you what it is, so let them get yoy checked out and then everyone here will help you get through whatever is needed.
