If a thyroid nodule is diagnosed as malignant, treatment usually involves surgery to remove the affected part or the entire thyroid gland. After surgery, radioactive iodine therapy may be used to destroy any remaining thyroid cancer cells. Hormone replacement therapy with thyroid hormones is often necessary to maintain normal body functions. Regular follow-up visits and tests are essential to monitor for recurrence. In some cases, targeted therapies or chemotherapy may be considered if the cancer has spread. The treatment plan is individualized based on the specific characteristics of the cancer and the patient's overall health. ????
