Hey Pgrady, All of the doctors that I’ve talk to seem to agree that radiation is the way to go on this. Maybe it’s just because the lymph nodes were lightly touched and this is more of a precautionary maneuver. As for HPV, I know nothing about it. My cancer was caused from years of smoking and drinking combined with some susceptible genetics. Heck of a way to quit smoking! Good luck to you too! May the radiation be gentle to both of us 👍
