[|Human|] 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.
[|AI|]  HI Welcome to Chat Doctor Yes as there was radiation exposure you are at risk of developing thyroid cancer. And biopsy is a good method but as the doctor said that nodules are so small to take biopsy then you have to wait for 1 year to undergo ultrasound thyroid to see if the nodules have increased in size or number or not. Till then be careful about your thyroid hormone status. And try to keep TSH within mid-range. If you have any further query then you can come back to Chat Doctor I will definitely help you.
