"Gastric cancer is one of the most common digestive tract tumors, which seriously threatens people's life and health. The prognosis of gastric cancer is closely related to the time of diagnosis and treatment. The 5-year survival rate of advanced gastric cancer is still less than 30% even after surgery, while the 5-year survival rate of early gastric cancer is more than 90% after treatment.
However, about 90% of gastric cancer found in China belongs to advanced stage, which is extremely unfavorable to the prognosis of patients. To improve the survival rate of patients with gastric cancer and reduce the mortality rate, the most effective way is to screen for gastric cancer in the general population.
