I feel like the ent saw something on the u/s to change his mind as abruptly as he did. He prepped me for the chance that the nodule is cancerous and what to expect. Obviously I should have asked more questions but due to shock taking over I was at a total loss.
If it were me, I think I'd get the FNA and if it's benign and causing no symptoms, have them follow it up with am ultrasound yearly. In any event according to the American Association of Clinical Endocrinologists, PEI (alcohol injection) is the treatment of choice for complex nodules.
I'd get a second opinion.
