The effect of iodine nutritional status on thyroid cancer has been controversial for many years. We designed a prospective cohort study that recruiting patients in different iodine areas who underwent thyroid cancer surgery in branch hospitals from 2012 to 2019，and follow up their clinical outcomes. We aimed to analyse the relationship between regional iodine nutrition level and pathological types, clinical features, and prognosis of thyroid cancer.
