This is just my opinion.............if you have nodules of any decent size, get them biopsied. Even a biopsy can give inconclusive results. Have you had an ultra sound to see how big they are ? That is how they usually determine the size.
I have 2 of them. I had the large one biopsied last July and am thinking now about getting it removed.
The FNA is nothing to worry about, It is pretty painless and it takes just a few moments. If you have to have one, don't worry about it too much.
I can relate. I have a small nodule inside the right thyroid lobe. They performed a biopsy due to my family history of thyroid cancer, but were unable to get an adequate specimen. I will be going back for a follow-up ultrasound in October. Hang in there! Does anyone know if nodules can interfere with your thyroid medication? I continue to have problems and my dosage keeps needing to be bumped up. It doesn't seem like the medication is helping at all.
