The association of obesity with thyroid carcinoma risk

Background The prevalence of obesity and an increased incidence of thyroid carcinoma (TC) threaten public health in parallel on a global scale. Sufficient evidence supports excess body fatness in thyroid carcinogenesis, and the role and anthropometric markers of obesity have been causally associated with the rising risk of TC. Methods A literature search was conducted in PubMed. Studies focused on the effect of obesity in TC. Results This review mainly discusses the global incidence and prevalence of obesity-related TC. We also review the role of obesity in TC and potential clinical strategies for obesity-related TC. Conclusions Excess body fatness in early life and TC survival initiate adverse effects later in life.
