As the most common malignant tumor of the thyroid gland, the exact cause of thyroid cancer is not clear, and the pathological types include papillary, follicular, medullary and undifferentiated carcinomas. The long-term prognosis of papillary, follicular and medullary carcinomas is good with timely radical surgery and postoperative chemotherapy or even radiotherapy. After thyroid cancer surgery, we advocate a high-protein, low-fat diet and avoid eating too oily, spicy and stimulating foods. Shrimp is a high-protein nutritious food, which will not lead to tumor recurrence or metastasis and can improve the nutritional status of patients with thyroid cancer, so patients with thyroid cancer can eat shrimp after surgery.
