How to prevent liver cancer

Liver cancer is the result of the synergistic effect of multiple factors, and its occurrence is multi-stage. Due to the effects of biological factors, chemical factors, etc., irreversible changes occur in the DNA of liver cells, and at the same time or followed by the cancer-promoting stage, the expression of cell genetic information is mainly changed, and immune surveillance cannot play a role, eventually forming cancer foci.

1. Prevent hepatitis: Using hepatitis vaccines to prevent hepatitis and thus liver cancer has become one of the most promising ways to prevent liver cancer, but it is estimated that it will take decades to see results. It has been proven that hepatitis B vaccines are effective in preventing hepatitis. However, from a comprehensive perspective, prevention of HCV and HDV still needs to be considered. In addition to injecting hepatitis B vaccines, prevention of viral hepatitis also requires attention to the control of other transmission routes, such as diet, surgery, blood transfusion, injection, acupuncture and hairdressing.

2. Grain mold prevention: Mainly for corn and peanuts that are easily contaminated by AFB1. Moisture-proof storage is carried out during grain harvesting, threshing, transportation, drying, storage, etc. Grain that has been obviously moldy cannot be eaten; grain that is extremely mildly moldy is carefully selected, cleaned, and treated with drugs. In high-incidence areas, it is recommended to change the dietary structure and reduce the proportion of corn in the staple food.

3. Improve drinking water: In rural areas with high incidence, adopt a variety of measures in conjunction with the patriotic health campaign to improve the drinking water environment, switching from drinking ditch and pond water to drinking well water, deep well water, and rainwater, or building small water plants. Cities should use unpolluted water sources as tap water sources and prevent environmental pollution.

4. Appropriate selenium supplementation: For people with low selenium level, use selenium-rich yeast, selenium polysaccharides, and selenium-rich salt to supplement selenium and increase blood selenium levels.

5. Other preventive measures include reducing nitrite
