RESUMO
Gastric cancer is a common malignant tumor in China, which seriously threatens the health of people. With the deepening of research on the prevention and treatment of gastric cancer in China, especially the effective control of risk factors related to gastric cancer and the continuous improvement of the level of screening and diagnosis and treatment of gastric cancer, the prevalence and mortality of gastric cancer in China are declining year by year. Although great progress has been made in the prevention and treatment of gastric cancer in China, due to the aging of population and large population base, gastric cancer is still the third most common malignant tumor and the second most lethal malignant tumor in China. It is still one of the major diseases endangering the health of Chinese people, and there is still a long way to go for its prevention and treatment, and further efforts should be made. This article reviewed the epidemiological changes and implications of gastric cancer in China.
