Iodine 131 treatment is usually required for thyroid cancer patients who have residual thyroid tissue after total thyroidectomy.
Iodine 131 is a kind of radionuclide. Since thyroid tissue has the function of taking up iodine 131, the beta rays emitted by iodine 131 can be utilized to destroy the residual cancer cells, which can play a therapeutic role.
Thyroid cancer patients, even after total excision surgery, who are found to have residual thyroid tissue after surgery and whose iodine 131 uptake rate is >1% need to undergo treatment with iodine 131.
The choice of specific treatment options should be made under the guidance of a physician.
