Thank you Charm and Karen. My cancer is not connected to HPV and I am not a smoker or drinker and I was diagnosed at age 42. All I can say is that ALL of my docs in NYC asked me if I was a long term mouthwash user and they all feel it is a cause of oral cancer. Yes, it would be difficult to prove, but other than mouthwash there is no reason at all that I should have gotten this cancer.
