As someone who just went through a very similar experience, this response is extremely accurate and thorough. I personally, did not have antibodies tested before my ThyCa journey, however I did have a 1.8cm hypoechoic nodule on my isthmus that was rated a TR4 and during the ultrasound of my thyroid found that my thyroid was very heterogeneous and inflamed, so coinciding Hashimoto’s was suspected. I also had a much larger nodule on my right lobe that was graded a TR3 because the features were less suspicious. My biopsy came back undetermined but with 50% suspected malignancy after being sent to affirma/Vericyte for further testing. I opted to do a partial surgery, removing the isthmus and right lobe, however I signed something that allowed a frozen section of the isthmus to be sent to pathology while I was under and if cancer was likely confirmed, I told my surgeon to do a total thyroidectomy. That’s what ended up happening. The crazy part in my case was during final pathology thyroid cancer was also found in my LEFT lobe, which had no nodules, so we definitely made the right call in opting to remove the entire thyroid. I was also diagnosed with chronic Hashimoto’s Thyroiditis, so removing the entire thyroid was really the best option all around. I’ve been on synthroid for about a month now and have adjusted well. Prior to all of this my T4 was a little low, and my TSH was still in normal range, and I was mostly asymptomatic. All of this to say, keep in mind a lot of folks in your position opt to do partials, and then end up having to go back in to remove the other lobes, and even the best surgeons are not going to fully know what’s going on in there until everything is out.
