I had PTC with follicular variant in 2016. I had for decades felt I had thyroid issues but no doctor would pursue it other than running TSH tests. In my path after surgery, I had chronic Hashis. My cancer was only on one side, but because the margins were close to the edge my surgeon took it all. I was glad after I saw my path report. Pros: you can control your medication levels to the point you could be more comfortable symptom wise. Cons: while they have come way down, I still show antibodies. I did have an ablation at the insistence of my endocrinologist. I am 100% dependant on thyroid replacement medication for life. I periodically get symptomatic when my thyroid levels are too suppressed. If you have time to consult with an endocrinologist who treats thyca, that is what I would suggest- to get one more opinion before surgery. You should have one lined up to follow you afterwards.
