Overwhelmed by treatment options??

Papillary thyroid cancer that has spread to my lymph nodes. Had a partial thyroidectomy in Sept and waiting to get more tests to determine extent steps. It was a surprise finding as the biopsy done where I live was negative
Everything from neck dissection to radiation to simply active surveillance has been tossed around
I am not super excited to have RAI, anyone ever do beam in a situation similar to maintain half thyroid and not be totally irradiated ? So many ways to progress and just overwhelmed
Sending light and prayers to you all!
