After a complete thyroidectomy for PTC in 2021, I was referred to a radiation oncologist for a recommendation as to whether RAI was indicated. My risk factors were my age (70 at the time of my surgery), the fact that my nodule had slightly breached the capsule, and the size of the nodule that had been removed. On the positive side, the pathology report after my surgery said that the margins had been clean and there had been no apparent lymph node involvement. We discussed this and decided together that watchful waiting was a reasonable strategy and that we would regularly evaluate my TSH suppression and presence or absence of thyroid antibodies, and do regular ultrasounds to see if there were any signs of cancer recurrence. My cancer was staged as 1b. Four years out things still look good. An ultrasound 3 years out showed residual thyroid tissue in the thyroid bed but my thyroid suppression is good and I my bloodwork has not shown any signs of thyroid antibodies. The residual tissue did not look cancerous at this point and there were no concerning lymph nodes. So I continue watchful waiting under the care of an endocrinologist who is very experienced with thyroid cancers. I think you would benefit from having an endocrinologist who is experienced in treating thyroid cancer and perhaps an evaluation with a radiation oncologist who will partner with you in these decisions. Make sure you understand everything so that you can make a well informed decision.
