I have had radiation to my brain in 1998. I have also been treated for Hypothyroid since 1990. I have recently had a hard time keeping my TSH 3 within limits. I had a Thyroid U/S last month and they identified several heterogenous, hyper vascular nodules, nodule Nodule 1- 1.6 X 1.1 X .9cm and Nodule 2- 1.8 X 1.4 X 1.1cm I was scheduled for a U/S biopsy today, and they canceled saying the nodules were to small and they want to follow up in 1 year. To my understanding, due to they fact that I have had Radiation treatment in the area I am at higher risk for thyroid cancer . Is this an acceptable protocol for my situation.
