Esophageal cancer radiotherapy is a very effective treatment method, which can significantly reduce esophageal tumor size and significantly improve symptoms of eating obstruction. Some patients with early esophageal cancer can survive for a long time after radiotherapy. However, patients with advanced esophageal cancer still need radiotherapy and chemotherapy, so as to better control the disease. Most patients receive radiotherapy for esophageal cancer. After completing 30 times, 60Gy is enough. only one course of radiotherapy can be done for the same site within one year. If the condition is stable for more than one year and the tumor recurs again, please ask the radiologist to evaluate whether radiotherapy can be performed again.
