The therapeutic effect of stomach cancer is relatively optimistic among the tumors of the whole digestive tract at present. Because of the whole digestive tract, from hypopharyngeal cancer, esophageal cancer to stomach cancer, and then to intestinal cancer, colon cancer, rectal cancer, and anal canal cancer, the therapeutic efficacy of stomach cancer is relatively optimistic among the whole digestive tract tumors. Malignant tumors generally use 5-year survival rate to evaluate its efficacy. For stage I gastric cancer, the 5-year survival rate is more than 90%; for stage II gastric cancer, it is about 60%; for stage III gastric cancer, it is about 30%; and for stage IV gastric cancer, it is about 10%. This kind of treatment effect suggests that the earlier the treatment, the better the treatment effect. Therefore, for the sake of one’s safety and health, it is necessary to have regular gastroscopy checkups every year in order to detect early gastric cancer in time, so that the treatment effect will be better and the quality of life will be more guaranteed.
