Nutrition and diet improvement: In the past, the high incidence of gastric cancer in some areas was related to eating habits, such as high salt, high fat and high temperature food. Modern people pay more attention to healthy diet, eat more vegetables, fruits and fiber foods, and reduce the intake of some carcinogens.

Hygiene and food safety: The improvement of modern hygienic conditions and food safety standards will help reduce the risk of gastric cancer. Hygienic treatment and storage of food can reduce the risk of bacterial and viral infection and reduce the infectious factors that may lead to gastric cancer.

Control of Helicobacter pylori: Helicobacter pylori is a bacterium related to gastritis and gastric cancer. Screening and treatment of Helicobacter pylori in developed countries such as the United States is helpful to reduce the risk of gastric cancer related to this bacterial infection.

Early diagnosis and early treatment: The progress of modern medical technology makes early diagnosis and early treatment possible, and gastric cancer found early can be better treated.

Lifestyle change: Americans are more aware of unhealthy lifestyles such as smoking and drinking, and more people choose to quit smoking and limit alcohol, which reduces the risk of cancer.

Health education: The popularization of health education can help people better understand and prevent diseases such as gastric cancer, and make the public consciously take preventive measures.

It should be pointed out that the incidence of gastric cancer is related to many factors, including genetic factors and environmental factors. Although the prevalence of gastric cancer in the United States has declined, it may still have a high incidence in other regions. The popularization and implementation of comprehensive measures and the improvement of public health awareness will help reduce the risk of gastric cancer.
