Wow. This is news to me too. Mine was strictly on the tongue, and I mean tongue as we laymen think of it, not as doctors do, and it was
HPV+. Now I hear that all that treatment stuff may or may not have mattered and doctors were telling me I'm gonna be fine because of the good prognosis when that may not be the case? Sheesh. No wonder some of my supposedly good doctors seem so flaky lately. (And no, there was no spread elsewhere, not even lymph nodes, though it did recur in the same area.)
Gah.
You have all my sympathies, for sure, Marv. It's a crazy ride no matter what answers you get.
