I have moved your post to its own thread. Where you posted previously, that member has not returned after making only a couple posts. Usually that leads us to believe there was nothing seriously wrong or they would have continued to ask questions.

Do you use tobacco products of any kind? If so, stop immediately and give your mouth a chance to heal itself. Tobacco, weather its chew or cigarettes is full of known cancer causing additives. If you drink alcohol of any form, stop drinking until you find out whats wrong. Alcohol will burn sensitive mouth tissue. Believe it or not, this includes strong mouthwash like Listerine so check the label for alcohol content.

It could be any number of things besides oral cancer. I hope its nothing serious! Get a biopsy and stay busy while you wait a week for the results.

Best wishes!!!
