Han MA, et al. - In this meta-analysis, researchers focused on the link between exposure to persistent organic pollutants, pesticides, and thyroid cancer. They reviewed 15 studies identified from the PubMed, Embase, and reference lists of relevant articles. The meta-analysis included 8 studies. An increased risk of thyroid cancer was evident in relation to exposure to pesticides. Findings revealed an increased risk of thyroid cancer in relation to herbicide exposure and agricultural exposure to pesticides. In addition, the robustness of the results was demonstrated in a sensitivity analysis.
