Thyroid cancer recurrence: does radioactive iodine dose matter?

Patients should be followed-up for more than five years, say researchers

A low dose of radioactive iodine for ablation appears just as effective as a high dose for patients with low or intermediate risk differentiated thyroid cancer, researchers say.

Long-term follow-up of the UK HiLo study found the patients receiving a low dose were at no greater risk of cancer recurrence.
