Regardless of benign or malignant thyroid tumors, recurrence is possible after surgery, but the chance of recurrence is not very high and may be related to one’s own physical condition, genetics, emotions, environment and other factors. The thyroid gland is a hormonal target organ, and as long as there is hormonal abnormality, recurrence may occur. In case of benign tumor recurrence, the size of the tumor and its impact on the patient should be used to determine whether surgery is needed. If the tumor affects the appearance or shows symptoms of pressure, timely surgery is needed. In case of malignant tumor recurrence, treatment needs to be based on whether it affects the quality of life and the lymph node metastasis. Radical surgical procedures can be taken as a good curative effect can be achieved. After treatment again, patients should remember to review on time, pay attention to the regular diet and eat more nutritious, well absorbed and digested foods, such as fresh vegetables and fruits, beans, mushrooms and other foods. In life, pay attention to keep the bowel movement smooth, keep the mood relaxed, avoid anger and exertion, etc., and eat less fried, pickled, smoked and high iodine food.
