Thyroid diseases are very common, and the most common malignant tumor of the thyroid gland is thyroid cancer. In recent years, the incidence of thyroid cancer is increasing, and as the number of patients with the disease increases and the disease becomes more common, the clinical treatment methods are becoming more and more sophisticated. So, how long can you live after thyroid surgery? Thyroid cancer is a very serious disease, but it has a higher chance of survival than other cancers, and most of them grow more slowly and have a lower degree of malignancy. The time to recurrence of thyroid cancer cannot be determined, but most are five years. The extent of surgical resection of thyroid cancer affects the recurrence or metastasis of thyroid cancer. Data show that the recurrence rate is 10% to 20% after combined radical neck surgery, 20% to 30% after resection of the tumor and its affected thyroid lobe, and 40% to 60% after resection of the tumor alone. In addition, the recurrence rate of thyroid cancer is mainly determined by the degree of malignancy, and there is a positive correlation between the two. The duration of life expectancy after surgical treatment of thyroid cancer is closely related to the physical condition of the patient. Most patients are able to avoid recurrence even if they actively receive treatment and exercise. Therefore, patients should actively treat and take care of their body after surgery, and go to the hospital for regular review. Patients with early-stage thyroid cancer need to maintain a good state of mind and improve the effectiveness of treatment through surgical treatment combined with dietary regimen. Patients with advanced thyroid cancer, although the treatment effect is not great, should also improve the treatment effect through dietary management. Patients should eat more iodine-rich foods, such as kelp and nori, and more rich and high-protein foods. Eat more fresh fruits and vegetables, eggs, etc. Besides, thyroid cancer patients should eat more foods that can strengthen the body’s immunity, such as turtle, shiitake mushrooms, walnuts and turtles. They should also eat more foods that help wound healing, such as greens, taro and other foods that have the effect of reducing swelling.
