I have never had an anuersym but I have had thryoid issues. Had Hashimotos and a thyrotoxic condition (they could not control it) so we took it out.

Make sure they do a calcitonin test. Blood test. That test is an indicator of whether there is a predispoition for thryoid cancer I believe.

They will also want to biopsy the nodules. Not too painful and over in 5-6 minutes.

Good luck.
