Question

Is it better to have a diet with or without iodine products to prevent thyroid cancer? Does using iodized salt increase your risk of cancer?

Answer

Kolin Hoff, MD, Endocrinologist at Penn Medicine responds,

Iodine deficiency increases the risk of goiter but does not increase the risk of cancer. Nodular goiters have about a 5% or less risk of cancer. Using iodized salt does not increase your risk of cancer.
