Peridontists are not cancer doctors nor, in my opinion, should they be saying things like that! I have never had a doctor actually say it was cancer until they KNEW it was. They always withhold a diagnosis until they have evidence, so I wouldn't put any stock in what he said.

Until you actually get some results, try to stay as calm as possible. I have had numerous lumps and bumps on my tongue and neck and have found that worrying doesn't improve them, and magically some of them just repair themselves. Turned out I had bitten my tongue or some such.

Get the biopsy - try to stay calm. And, crap that these worries are back with you.
