Replying here to my original post so hopefully everyone will see it.

Today I had my first appointment with my oncologist to talk about what they found and what my options are. The good news is that there were no other spots visible on the scans, anywhere on my body besides my neck lymph node.
Because of this, I am 99% sure that I will be taking a very conservative treatment, namely removal of this lymph node with continued follow-up at Moffitt. We do not know how long this new surgery will take to set up, but we hope to still be able to go up to Rhode Island, even if only for a couple of months.
If it recurs in the future, I will probably take one of the immuno-therapy treatments.
Thanks to all for sharing your stories.
