After gastric cancer is removed, the specific survival period depends on the patient’s own condition as well as treatment, and also takes into account various factors such as the patient’s age, physique, living habits, psychological factors and so on. If a stomach cancer patient finds that the situation is already more serious after stomach removal, after stomach removal if the patient actively cooperates with the treatment, chemotherapy or radiotherapy will be carried out at a later stage. If the effect is good, the cancer cells have not metastasized and the postoperative care is proper, the patient’s resistance is good and the daily nutrition is sufficient, the survival period of 50% of the patients can reach 5 years. If the patient’s physical quality is poor, his psychological quality is poor, his living habits are bad, and the effect of postoperative treatment is not very remarkable, the survival period usually will not exceed 2 years.
