The prevalence of thyroid nodules within a given population depends on a variety of factors that include age, sex, diet, iodine deficiency, and therapeutic and environmental radiation exposure. Thyroid nodules are found in approximately 1.5% of children and adolescents. They are more common in females, and this predisposition exists throughout all age groups. In fact, palpable nodular disease is 6 times more common in adolescent females compared to males of the same age.
