Welcome again.... Just want to reinforce Christine's observations. I just went through the left tonsil cancer spread to lymph nodes, non smoker, minimal
drinker, HPV. The approach was different, they dug and biopsied first to pinpoint the original tumor (tonsil), then the tonsilectomy, then neck dissection to remove all lymph nodes, then test nodes to determine stage, decide on radiation.

Another opinion from an experienced cancer center would really make sense..
