Radiation and thyroid neoplasia
It is now generally accepted that an association exists between external radiation administered to the head, neck, and upper thorax of infants, children, and adolescents and the subsequent development of neoplastic changes in the thyroid gland. Until recent years, external radiation was frequently administered to shrink an enlarged thymus or for the treatment of tonsillitis, adenoiditis, hearing loss, hemangioma, acne, tinea capitis, and other conditions. During the course of these treatments, the thyroid gland was exposed to scatter radiation. The use of external radiation therapy was then accepted practice, and its value was attested by many. Concern about the adverse effects was not initially appreciated, primarily because of the long periods of time between the radiation and the recognition of changes in the thyroid. The availability and effectiveness of other therapeutic measures and the growing concern about the delayed effects of radiation therapy when administered to the young for relatively benign conditions has, in recent years, largely eliminated use of this form of therapy, except in a few unusual conditions.
