It sounds like your dentist did a good job and helped to ease your mind. Im very sorry an exact diagnosis wasnt possible. Your dentist is correct, only a biopsy will determine exactly whats going on. Thats why I suggested to head right to the ENT, so a biopsy could be taken.

Remember, our site consists of OC patients/survivors and caregivers not medical professionals or anyone with a medical background. My knowledge is mainly about oral cancer and not so much about other mouth conditions (like what your dentist mentioned).

As far as the surface measurement goes, Im very sorry but thats not possible to answer either. The size you see may or may not be a true reflection of how big the spot really is as what lies under the surface could be very different than what visible on top. It could be like an iceberg (huge underneath the surface) or it could be the same as what you see. Only a doctor thru either a CT or MRI would be able to determine the exact size or the lesion.

You are on the right path. It takes time to get a complete diagnosis. In my opinion, its unlikely anything has significantly changed since the sore was first discovered. Staying super busy will help the time pass until you find out what your lesion is.

Hang in there!!!
