Welcome,
If you haven't already, it's a good idea to obtain written copies of the final pathology report for your records, and future reference. In some cases, 2nd opinions will require the original biopsy slides.
In the near future, like on Friday, the worlds first oral cancer screening test will debut. The OraMark oral rinse test is capable of detecting cells responsible for oral cancer at their earliest stages. I've seen others that use oral screening light with fluorescence to identify cancer, pre-cancer, and other abnormal lesions by dentists, , but not sure if it's used by many ENT's, other than some similar types used during surgery, so all this may be helpful in the future, including liquid biopsies being developed instead of the watch and wait.
