I'm like you Brenda, I have no idea. No one listened to me either for a long time. I knew I had cancer and they would just blow me off in the erooms. If I wouldn't have had my 3 month scope scheduled and been thinking ?? I asked My Dr that operated on my esophagus and ans abdominal anneurysm, if he would check out my mouth and tongue. When i woke up he told me he already made an appy for me with a very good cancer surgeon. Man I was glad i remembered to ask him. At least you know you were right and when you find out bout the reading,, post it will you? Good luck and best of wishes.
