My tongue had been sore for over a year. I had been to the eroom quite a few times because of infections from my sinus and phneumonia. Each time the Dr would look in my mouth after I told them my teeth had been breaking off and my fillings falling out. Not one Dr mentioned oral cancer until the surgeon that does my scopes every 3 months for Barretts Esophagus , had just finished a scope on my throat, and told me he had made arrangments for me to see a cancer specialist to check my tongue. Yep, good old cancer. Make sure you do what you say you are going to do. Don't put it off like I did. Go for the Gold man and find a good Dr.
