Whether a nodule on the right side of the thyroid is serious or not is based on the nature and size of the nodule. If a nodule on the right side of the thyroid gland has clear borders, uniform echogenicity, regular shape and a volume of less than 2 cm, it is considered a benign lesion that is not seriously harmful to the human body, and patients are advised to review the thyroid ultrasound regularly. Second, it is a benign lesion nodule, but a huge nodule compresses the body’s trachea and esophagus, causing swallowing and breathing difficulties. This has a heavy impact on the human body and patients are advised to have surgery to remove it as soon as possible. If the patient has a thyroid nodule with rich blood flow at the border and internal calcification and malignant signs such as nodule aspect ratio greater than 1, it is recommended that thyroid puncture be performed as soon as possible to clarify the nature of the lesion and, if necessary, surgery.
