Advances in the relationship between iodine and thyroid carcinoma / 中华地方病学杂志

ABSTRACT

In recent years,the incidence rates of thyroid carcinoma (TC) in many countries have been increasing rapidly,especially papillary TC.But the reasons are not yet unified.The main influencing factors include improved diagnosis methods,increased screening,radiation exposure,mental stress,body mass index (BMI) and obesity.The role of iodine intaken in TC remains uncertain.It is generally believed that iodine deficiency is a risk factor for follicular TC;and excessive iodine intake can rise the constituent ratio of papillary TC.
