In my recollection of staging, multiple lymph nodes, even if on only one side, put in in the Stage IV arena. Mine was also a 2cm primarty, although at BOT. I also had bilateral ND, with 1 obvious node and another microsocpically suggestive of involvement, both on the right.
17 months after the end of treatment, I am doing pretty much whatever I want, with some limitations from the ND and radiation fibrosis, but more annoyances than anything. Just had my most recent follow-up with the RO, and everything looks good. So the key is to get yourself to the best cancer facility you can, do EXACTLY what the doctors tell you to do, and stay active and positive.
We have all been there, done that, got the T-Shirt, so never be afraid to ask any question or vent any feelings.
