Cathy,

As you can see by my signature below, I've been dealing with oral cancer since 2005, had a recurrence in 2010, and dysplasia in 2011 - all the same area as my original tumor. Over the years I've had a few sore spots pop up on my tongue (both sides), and for the most part they resolved themselves within a week.

The general rule is if the sore is there for 2 weeks or more to have it checked out. For now I would keep an eye on it - take a good look in your mouth with a flashlight, perhaps take a picture or have someone else take a look, so you can watch for changes (getting bigger or smaller, color, etc.).

If it doesn't go away soon, contact your doctor to have it checked out. If is better to have your doctor check it out than to keep worrying that it could be cancer again.

Wishing you the best!
