After one year of radiotherapy for esophageal cancer, radiotherapy is usually not carried out for the original site anymore because the accumulated radiotherapy dose will cause irreversible damage to the organs. Recurrence of esophageal cancer after one year of radiotherapy will cause irreversible damage to the surrounding organs due to the cumulative effect of radiotherapy dose, therefore, generally no more secondary radiotherapy will be conducted at the original site. Relevant auxiliary examinations can be perfected under doctor’s guidance to comprehensively evaluate the condition, and chemotherapy, immunotherapy and other methods can be considered. Patients with esophageal cancer should ensure balanced nutrition and give high-calorie, high-protein, high-vitamin and low-fat diets. They can choose to eat more fish, eggs, milk, soybean products, apples, bananas, kiwis, cauliflower, shiitake mushrooms and so on, to provide the nutrients needed by the organism and to improve the immunity.
