Introduction: The bidirectional relationship of risk between breast cancer (BC) and thyroid cancer (TC) has been debated. Estrogens are proposed as agents implicated in the risk of developing TC promoting thyroid tumorigenesis. Therapies that reduce the effect of estrogens on their receptors in cancer cells are widely used.Objective: To correlate the use of hormonal therapy in BC with the prevalence of TC.Material and Methods: We p...

Introduction: Some studies suggest a possible link between autoimmune thyroid disease (AITD) and thyroid cancer (TC). However, existing data is inconsistent, and no consensus exists regarding this question.Objective: The aim of this study was to analyze the association between TC and AITD, namely Hashimoto’s thyroiditis (HT) and Graves’ disease (GD).Methods: We conducted a retrospective and observational study of all pati...

Introduction: The prevalence of palpable thyroid nodules in Graves’ disease (GD) is approximately 15%. Cytopathologic interpretation in GD is challenging due to frequent cytomorphologic changes, namely after radioactive iodine (RAI) therapy. Some of the few published studies regarding fine-needle aspiration (FNA) in patients with GD, suggest an increased risk of malignancy of thyroid nodules arising in GD patients. However, the results are inconsistent, and there is no co...
