Thyroid nodule 8 x 11 x 12 mm is the reported result of the ultrasound. If the thyroid ultrasound does not suggest signs of malignancy, follow up is sufficient; if it suggests malignancy, further puncture is recommended to confirm the diagnosis of malignancy and then treatment through surgery. Consultation with relevant professionals is recommended. 1. Follow-up: mainly for patients who have benign nodules indicated by thyroid ultrasound and have no symptoms, the doctor will follow up with them, and the patients will go to the hospital regularly for physical examination and thyroid function test, so as to detect the possibility of cancerous nodules in time. 2. Surgery: For malignant thyroid nodules, the conventional treatment is surgical resection, regardless of the size of the nodules. The part of the thyroid gland to be removed includes not only the nodule, but also part of the surrounding thyroid tissue, or even most or all of the thyroid gland. Patients with thyroid nodules 8×11x12mm are advised to go to a professional and regular hospital to avoid adverse consequences.
