How long can one live with conservative treatment of esophageal cancer is mainly related to the degree of progression of the disease as well as one’s physical condition, which may be around 1~5 years. Early detection and early standardized treatment are recommended to get a better survival period. Esophageal cancer is a common malignant tumor in the digestive system, which may be related to heredity and personal diet. If the patient’s condition is relatively mild and belongs to the early stage of esophageal cancer, through conservative treatment, the survival period of the patient may be about 5 years, mainly because the primary lesion cannot be eradicated, the cancer cells will continue to grow, and systemic metastasis will occur with poor prognosis. If esophageal cancer is in advanced stage, through conservative treatment, the survival period of patients will be shorter, about one year, or even shorter, because patients with advanced esophageal cancer may not be able to eat, and the eating situation will gradually deteriorate, and the body lacks nutrition, which will reduce the survival rate. Once esophageal cancer is diagnosed, it is suggested that one should go to hospital and choose reasonable treatment plan under the guidance of doctors to prolong survival and improve prognosis.
