What are the side effects of radioactive iodine? Is it always a cure for thyroid cancer?


Kolin Hoff, MD, Endocrinologist at Penn Medicine responds:

The most common long term side effect of radioactive iodine in damage to salivary glands. Short term side effects are change in taste. Radioactive iodine is usually given to ablate the remaining thyroid tissue and help in monitoring for a recurrence. Radioiodine may or may not "cure" thyroid cancer if it has spread.
