Depending on where you live: Mayo clinic or Memorial Sloan Kettering in NYC.

In my opinion, there seems to be a lot of false positives, so if you had an FNA which gave results of possible cancer, and your nodule is small and not impacting any other structures, waiting awhile to see if it grows is worth it. There seems to be many stories of people who had thyroidectomy only to find out that it wasn’t cancerous (false positive). From what I understand, most thyroid cancer is slow growing and stays self contained. Some doctors might just want to eliminate the possible issue, however now that there are options for shrinking nodules (radiofrequency ablation) waiting to see seems like it might save people from thyroid surgery and the possibility of lifelong medication (which can be very hard to get regulated). In my opinion, waiting with frequent observation is worth it. If the nodule is growing, it might be worth going to a doctor who specializes in radiofrequency ablation to see if you are a candidate. They can assess the situation to determine if the nodule is cancerous (Affirma testing has the highest probability of predicting cancer) to see if you are a candidate. Shrinking the nodule could save your thyroid. Good luck!
