Tongue seems a little swollen and I have, what I think, is a taste bud inflamed.It is located on the top almost center of the
tongue. Irritation in mouth seems to happen after stomach upset. Several months ago it happened and I nipped off the top
white dead part and it was level with the rest of tongue but it is happening again.-same spot. It is a little smaller than a
pencil eraser and I've bitten it several times. The top is turning white again. The bump still has nerve ending because it is
painful. I'm worried about what it is (cancer) and don't know who to see about it and having it removed.
