Hello: I had two inconcolusive FNA's. In fact, after the 2nd the doctor who performed it said there was no possible way it could be cancerous. My endocrinologist wasn't completely comfortable and I ended up having a 3rd- which resulted in the need for surgery. It wasn't until after the thyroid was removed did they determine it was cancerous.
I hope that all works out for you. Feel free to e-mail if you have any questions. Best of luck.
