Esophageal cancer has the possibility of complete cure. Esophageal cancer is a malignant tumor disease in which the primary tumor lesion occurs in the esophagus, and its prevalence and mortality rate are relatively high. Its etiology is still unclear, and it will lead to progressive aggravation of dysphagia symptoms. According to AJCC staging, patients with stage 0 and stage I esophageal cancer, if the tumor cells have not metastasized and spread, it is very likely for patients to have the lesions completely removed by endoscopic resection or surgical resection, so as to achieve the effect of completely curing the disease. However, the later the staging, the lower the possibility of cure and the worse the prognosis. The earlier the scientific and standardized treatment of esophageal cancer is carried out, the higher the possibility of curing the disease will be. Individuals are recommended to have regular medical checkups in order to have the chance of early detection, early diagnosis and early treatment of esophageal cancer.
