Given the indolent and slow growing nature of thyroid cancer, there is debate concerning which patients require treatment. The first line of therapy, radioactive iodine (RAI), acts similarly to a heat-seeking missile that travels through the body destroying thyroid cancer cells, Michael Tuttle, MD Hypothyroidism results in increased levels of TSH production by the pituitary, which stimulates uptake of the radioactive iodine by thyroid cells.
