Hi Amy, I'm sorry to read of your pathology re the positive node . Having it spill into the neck is not the best news.
I have been on this board for a few years now. Non HPV oral tongue cancers are aggressive and need to be treated aggressively. Hit this hard so that you dont have to be doing this again when your options may become more limited.
We live in New Zealand and our team told us that HBO would accelerate the growth of any remaining cancer cells. Certainly my reading confirmed that. Enough so that we opted not to do it.
Please get a 2nd opinion from a CCC as Christine advised. Research has proven that these centres achieve better outcomes for their Patients.
We have been through this twice ourselves and I don't wish that on anyone.
I wish you the best with your treatments.
Tammy
