Esophageal cancer is a very common malignant tumor of the digestive system and a malignant tumor located in the chest. If esophageal cancer is treated well, it is possible to survive for a long time, such as more than 20 years, 30 years, or even longer, which means it does not affect the survival period. Of course, it is not easy to determine how many years you can live, so we can only see it while treating. Generally, early and middle stage esophageal cancer can be cured by surgery, and after surgery, combined with adjuvant radiotherapy and chemotherapy, the effect may be better. For advanced esophageal cancer that cannot be treated surgically, only palliative radiotherapy can be considered, and it is possible to survive for more than 2 years, 3 years or even more than 5 years. The main symptom of esophageal cancer is progressive choking, and many patients’ nutritional status will gradually deteriorate because they cannot eat, which is not conducive to the recovery of the disease.
