Kale,

I agree with several of the others here that your chances of having cancer at this point are quite remote. However, your dentist needs to learn a thing or two if he dismisses the subject with "no, you nullified the possibility when you quit". I'm one of many people on this site who NEVER smoked or chewed tobacco, but still ended up with oral cancer. Unfortunately there still seem to be too many medical professionals who think if you don't fit the classic risk profile, you can't possibly have this disease.

Gary makes a good point that you should probably be seen by a skilled ENT for peace of mind.
