Well, it isn't cancer till the pathologist says it is. The number of benign things that occur like this in all of our mouths every day is staggering. It appears that you are doing everything correctly. Someone discovered "something" and you are doing exactly what should be done to get a gold standard black and white answer as to what it is. Now that you are on that very appropriate path, occupy your mind with other challenges, life is full of them. (An idle mind will certainly lean towards the exact thing you are trying not tho think about.)

Don't continue on the Internet looking for what if's� that won't be fruitful and it will only feed the paranoia that we all succumb to once in awhile.

Lastly, occasionally we come across an oral surgeon who thinks that by looking at something he/she can tell if it is or is not something dangerous, and decides not to take the tiny little biopsy. No one, until something is wildly so advanced that my gardner can tell you that it is cancer, can tell with any certainty that it is or is something dangerous visually in these very early stages. Insist that he do the simple little snip of it and send it to the pathologist that was asked of him by the first doctor. Accept nothing less. What people who do this should realize, is that when they make that kind of uninformed judgment call instead of following through, they will be on the receiving end of where the buck stops when legal action is taken for missing something. The safe thing (and totally correct thing) was done by the first dentist. He started you on a path to a gold standard answer, which most of the time will be nothing to be concerned about. Now the surgeon shouldn't weigh in with an "opinion", he should just snip a tiny piece and send it on. This is the appropriate chain of referral and patient custody in dentistry.
