If the multiple thyroid nodules are 0.6*0.7cm, they are benign nodules and do not need treatment, regular follow-up is sufficient. If multiple thyroid nodules of 0.6*0.7cm are malignant, they need treatment, which may include surgery, radiation therapy, and so on. Multiple thyroid nodules 0.6*0.7cm are relatively small nodules, whether treatment is needed should be judged according to the nature of the thyroid nodules, and patients are advised to undergo ultrasound examination. If the ultrasound examination reveals that the thyroid nodules are not rich in blood flow, and the morphology is regular, the border with the surrounding tissues is clear, and there is no calcification, it is mostly considered to be a benign nodule. If the patient does not have clinical symptoms, treatment is usually not needed, but should go to the hospital regularly for review. If ultrasound examination reveals that thyroid nodules have unclear borders with the surrounding tissues, and the nodules are irregular in shape, rich in blood flow, and calcified, they are mostly considered malignant nodules, and patients need to be treated. If thyroid cancer is identified, thyroidectomy, iodine 131 radiation therapy, etc. are required. It is recommended that patients with multiple thyroid nodules should seek early medical treatment and choose the appropriate treatment under the guidance of the doctor.
