Cindy, I certainly understand your anxiety at this time. I have just been there recently. Mine was white patches, and my dentist told me it was cancer on visual inspection. After second and third opinions and a biopsy, it turned out to be callous from chewing where I have no teeth. It sure didn't look like callous to me, but I'm here to say that you can still get good news. Congrats on quitting smoking, that's a big hurdle! Take this a day at a time and lean on the very special folks here. I did and I still come back to visit them even though I got a clear diagnosis.
Blessings,
RitaZ.
