David, I stopped smoking over 38 years ago and stopped drinking almost 15 years ago. HNC doesn't run in my family. I haven't been tested for
HPV, but I haven't been exposed to it for almost 15 years, if then.
Not only that, but I received a full course of conventional (XRT) radiation, yet, a new tumor emerged inside my tongue less that two and one-half years later -- There's more to this than we understand and I believe it foolish to think otherwise!
BTW, they have linked HNC to oxygen -- Nearly 100% of HNC victims have used the stuf for years! Prostate cancer has been found to be far more prevalent in males than in females!
