The procedure is a walk in the park, a little snip of tissue, or a little cirlce cut with a miniature cookie cutter.... it is the emotional waiting before and after (for the results) that is the tough part. What you are experienceing is normal anytime our health is brought into question. There are many things in the oral environment that mimic oral cancer, so a prudent and cautious doctor might send many non cancer patients in for biopsy just to be sure. Please post back your follow up, and if you wish to vent here about your anxiety over it all in the meantime, this is the place to do it. But rest asured that the procedure itself is nothing, and will likely take less than 10 minutes. Do not allow them to delay in getting the results back to you. In the US, that can be as quickly as a few days, and certianly less than a week. You should expect the same, and not be afraid to push for answers if they seem to be slow in the process, your emotional health is also at stake during this timeperiod.
