Pet Ct Thyroid Cancer Restaging
What can be done to reduce cancer risk after CT scan (chest). I m worried about thyroid cancer as it is related to chest CT scan.
Don't worry: Hello - the radiation exposure from one ct scan is low. You do not need to worry about thyroid cancer because of a ct. We are exposed to radiation throughout our normal daily routines and when we fly. If you'd like you can limit other exposures. Request pat-downs at security at airports instead of the scanner for example. I don't think you need to do anything, however. ...Read more

Not likely to work: If you received IV contrast with the ct scan, you will not be able to receive radioactive iodine in 2 weeks. It can take months for the iodine from the contrast to be excreted. You may be able to increase the rate slightly by taking a diuretic, but the best thing will be to wait at least 2 months. ...Read more

Blood test, nuc scan: Blood tests for thyroglobulin(tg) are very sensitive for persistent thyroid cancer. Tg is only found in active thyroid cells, and after surgery and rai ablation, there should not be any cells or tg left. Blood tests for tg can show if thyroid cancer is still present, and nuclear scans with a diagnostic or therapeutic dose of radioactive iodine can show where thyroid cancer is still present. ...Read moreSee 1 more doctor answer

ENT: Find an ENT (ear nose throat physician) to evaluate you. An ultrasound would be the most common first step, but since you say you are worried that you might have thyroid cancer, you may have already had one; ultrasounds sometimes create uncertainty by showing nonspecific thyroid nodules.
