Thyroid nodule 10mmx6mm, 10mm is 1cm, 6mm is 0.6cm, nodule size is 1cmx0.6cm. Thyroid nodules are formed by localized abnormal proliferation of thyroid cells, and a qualitative diagnosis of nodules cannot be made based on nodule size alone. The diagnosis should be based on the TIRADS classification of the nodule and the corresponding fine needle aspiration biopsy result. If the nodule is benign and there are no symptoms of compression, regular follow-up is sufficient. If the nodule is malignant, early surgery is recommended. Surgery is also an option for benign nodules with compression symptoms (dyspnea, dysphagia, etc.). Patients with thyroid nodules should be treated under the guidance of a doctor, and should seek prompt medical attention if they experience discomfort.
