Abstract: Thyroid carcinoma is a common cervical tumor. Its occurrence is associated with genetic and environmental factors. The incidence rate of thyroid cancer is increasing. However, the pathogenesis and the influencing factors of thyroid carcinoma are not yet fully understood. Many clinical studies and epidemiological investigations have found that such factors as radiation exposure, female hormone metabolism, and obesity have important links with the occurrence of thyroid cancer, but its association with factors such as dietary factors remains controversial. Therefore, it is urgent to explore and validate the relationship between various factors and thyroid cancer through epidemiological studies. In order to provide reference for the prevention of thyroid cancer, this special column “Thyroid carcinoma and associated risk factors” focused on the associations of female reproductive factors and dietary factors (including intake of iodine-rich foods) with thyroid carcinoma (nodules).
