Hi J - Glad you found this place so until someone else gets to you with more direct experience than I've had, do check the main pages of this forum - especially the Diagnosis page. I was the caregiver to my son, who was 33 at the time, he never smoked - and was diagnosed (after a biopsy) with squamous cell cancer under his tongue. It may not be anything serious at all in your case, but your health is very important so it is better if you can see en ENT with a lot of experience with Oral Cancer. Only a biopsy can tell for sure if it is or not. It's also a good idea to be treated at a Comprehensive Cancer Center where they use a team approach for the best chance of successful treatment. Let us know what happens, ok?
