Hello I also had my thyroid removed in march of 2020 it for cancer , And 1 Lymph node with with cancer I also declined the radioactive iodine Because of secondary things and just not being sure, I'm am monitoring now and my endocrinologist orders is blood work every 6 months And a ultrasound depending on my blood results There have been suspicious spots that they have seen but nothing that makes me have to do anything else at this point just monitor it. Good luck to you on your decision.
