Jon, I second Pam. Sounds very likely that your cancer, like mine, was caused by HPV. There are a number of very good research papers on the page she linked you to. I found them illuminating, and reassuring.... as evidence seems to point to those of us with HPV-caused disease having a much better outcome than the traditional smoking route.

Keep us posted on your progress!
