Welcome to the bus nobody really wants to ride. But we are a close and friendly bunch. I'm new but from everything I read concurrent chemo and radiation provides better outcomes. The platinum based chemo improves the effectiveness of the radiation.

And I never read yet that having the cancer HPV+ was a reason to not include chemo with the radiation.

I would surely do more research, get better informed, and ask some probing questions to get better answers why your treatment is not CRT rather than RT.
