• A: Routine diagnostic radiographs should fall well below the levels of radiation thought to increase risk of thyroid neoplasia. During more prolonged radiologic procedures that might expose the thyroid to higher doses of radiation, a lead neck shield is used. • Q: Should prophylactic thyroidectomy be performed in children identified genetically as having familial medullary carcinoma? • A: Yes, because of the poorer prognosis associated with development of this cancer.
