Thank you for the quick response.

The lesion was well differentiated in appearance (not sure if it is clinically well differentiated). We are not yet at a CCC, but are considering taking a second opinion once the biopsy results come in on this saturday.

My initial suspicion was Leukoplakia and was in bliss of ignorance and hope that it is not malignant. However, today was hugely disappointing.

Difficult to imagine the pain henceforth.
