Hi Bruce @buzzltyr57, welcome to the Connect H&N Cancer group. Your discussion is quite thorough which is to say very good in detail. It looks like you are on the right track including especially the feeding tube which is often overlooked. As annoying as a feeding tube can be, just remember that it too will be gone as well.
I was surprised by the addition of chemotherapy with the P16 result, which seems overly aggressive. I’m not a physician but I would want that treatment aspect justified. It’s uncommon at this stage.
Anyway although this will turn your life upside down, remember that tough times never last but tough people do. As most of us have experienced, this adventure will have some profound impacts on your life and often for the better. Hugs to you. And you know God is with you too.
