By the way, just to clarify, I have been having sinus and throat issues, and my left tonsil looks pretty weird. I'm not sure, but it could be the beginnings of SCC. It's all very frightening, and this forum has helped me out quite a bunch with symptoms and diagnosis. I'd like to participate and contribute in a meaningful, positive way.

Sorry if it seems like i'm being in-sensitive. I'm just trying to understand the nature of what we have to deal with. I worry for my wife and myself. Any preventive oral care is what I'm interested in.
