Thanks so much, everybody. I had an ulceration that had not healed in over 2 months, I asked my dentist to take a look and she said it looked very suspect and to see an oral surgeon asap. The oral surgeon also agreed that it would need to be biopsied and they did an excisional biopsy. I am a long time (46 years) smoker and definitely have some risk there. I am supposed to hear something today or tomorrow. So we will see.
