You should know the 3 causes of liver cancer and recommend several preventive measures for liver cancer

The two main causes of liver cancer and their preventive measures are as follows:

(1) Hepatitis B virus (HBV)

90% of liver cancer cases in my country have been infected with HBV, and the chronic hepatitis B infection rate among liver cancer patients is 10 to 20 times higher than that of the control group. The stronger the HBV index, the higher the risk of liver cancer. Chronic hepatitis B is related to cirrhosis. 80% (60 to 90%) of liver cancer occurs on the basis of cirrhosis, most of which is post-hepatitis cirrhosis.

Precautions:

Vertical transmission from mother to child and hepatitis B infection between 0 and 5 years old may be the main reasons for the permanent existence of hepatitis B virus carrier status. Therefore, in high-incidence areas and cities with conditions, newborns and susceptible people should be vaccinated with hepatitis B vaccine. The involvement of multiple hepatitis viruses and virus variants should also be considered, and it is not appropriate to rely on one measure alone. In recent years, it has been reported that hepatitis C virus (HCV) is related to 100% of liver cancer incidence, and the prevention of hepatitis C will become a practical problem in the future; in addition, attention should be paid to the transmission routes of hepatitis B and C, such as blood transfusion, injection, acupuncture, and shaving. People receiving dialysis, hemophiliacs, spouses of HBsAg carriers, medical workers, and especially those who come into contact with blood and blood products are also high-risk groups.

(2) Aflatoxin

Aflatoxin B1 (AFB1) is a strong chemical carcinogen for the liver and may be an initiator or promoter of liver cancer in humans. It has a synergistic carcinogenic effect with HBV. 10% of the residents in the high-incidence area of ​​Qidong ingest aflatoxin (derived from corn and peanuts in warm and humid areas), which is 10 to 100 times higher than that of Beijing residents.

Precautions:

Prevent food from getting moldy, strictly manage hygiene, and prevent ingestion of AFB. Remove or wash moldy food, reduce the intake of corn and peanuts in high-incidence areas, and encourage drinking green tea to prevent AFB from inducing liver cancer.

(3) The relationship between drinking water pollution and liver cancer deserves attention

There are many organic carcinogens and cancer promoters in lakes, ponds and ditches, as well as a type of blue-green algae that is easy to grow. Its toxic effect on the liver has been identified as another risk factor for liver cancer. In-depth research may reveal the mystery of drinking water and liver cancer.

Precautions:

Improve water quality and pay attention to drinking water hygiene, especially in areas with high incidence and serious industrial pollution. Rural areas should drink running water and well water, and cities should use less polluted water sources as tap water.
