How long you can live if you can eat and drink in advanced stomach cancer cannot be generalized, it is mainly related to the type of pathology, treatment method and physical condition. The earlier the treatment, the less the impact of the disease on life expectancy, so early treatment is necessary. Clinically, “5-year survival rate” is often used to roughly assess the survival of tumor patients. Early gastric cancer has a better prognosis, and the 5-year survival rate of intramucosal cancer is more than 91%, while the 5-year survival rate of submucosal cancer is between 80% and 90%. According to statistics, the 5-year survival rate of patients with stage I gastric cancer reaches 92.6%, the 5-year survival rate of patients with stage II is about 76.2%, stage III is 40.8%, and stage IV is about 6%. In addition, the survival period of gastric cancer is related to physical condition, pathological type, tumor stage and treatment. Early detection, early diagnosis and early treatment can improve the survival period and reduce the adverse effects of the disease. Therefore, it is necessary to seek medical treatment as early as possible.
