Thyroid nodules can be funny things... multiple nodules is usually a good indication that they aren't cancerous.
Have the FNA, see what they say, better to be safe than sorry. Not a very comfortable procedure but as I said, better to be safe than sorry.
Good luck with the procedure and try and keep positive.

If they are calcified, the chances are higher, but still only 15%. Are they vascular? Irregular borders? If vascular, I believe your chances rise to 20%. Get the FNA, you may have to have them removed.
