Background: Differentiated thyroid cancer (DTC) is the most prevalent endocrine cancer. Evidence showed a significant association between diet and DTC. Thus, this study aimed to assess the relationship between dietary intakes and DTC. Methods: This case-control study was accomplished among 300 adult patients and 300 matched (age and gender) controls in Mashhad city, Iran.
