Chinese medicine can be taken after radiotherapy for esophageal cancer. For patients with malignant tumors, it is recommended to take Chinese medicine throughout the treatment. For esophageal cancer patients, they are encouraged to take Chinese medicine not only after radiotherapy, but also before and during radiotherapy. Because the biggest factor that affects the completion of radiotherapy is radioactive inflammation. Once radioactive inflammation occurs, it may cause the patient to eat less because of mucosal edema and skin burns, thus reducing weight, which may lead to a decrease in nutritional status and eventually cachexia, and the short term weight loss of the patient will seriously affect the survival of the patient. In contrast, traditional Chinese medicine can reduce the toxic side effects such as radioactive inflammation and enhance appetite during the whole course of radiotherapy, thus improving the cachexia of patients, improving the quality of life of esophageal cancer patients, and also improving the completion rate of radiotherapy on time, so that the anti-tumor effect of the whole course of radiotherapy will not be reduced due to interruption.
