What is the cause of liver cancer

In recent years, liver cancer has become one of the major diseases that endangers society and human health, and it has brought great pain and distress to humans. In order to reduce the incidence of liver cancer, we humans should understand the causes of liver cancer:

(1) There are at least A, B, C, D, E, and G known hepatitis viruses. The main types of viral hepatitis and liver cancer are hepatitis B and C, namely HBV and HCV. About one-third of liver cancer patients have a history of chronic hepatitis. The positive rate of Australia antibody (HbsAg) is significantly higher than that in low-incidence areas. It has been found that hepatitis C virus infection, like hepatitis B infection, is closely related to the onset of liver cancer [1]. Hepatitis B virus and hepatitis C virus are definitely one of the factors that promote cancer.

(2) Approximately 50% to 90% of liver cancer patients[2] also have cirrhosis. In recent years, it has been found that the rate of hepatitis C developing into cirrhosis is no less than that of hepatitis B.

(3) Animal experiments have shown that aflatoxin B1, a metabolite of aflatoxin, has a strong carcinogenic effect and is present in moldy corn, peanuts and other foods. In areas where food is seriously contaminated by aflatoxin B1, the incidence of liver cancer is also high. Nitrosamines, azo mustards, alcohol, organochlorine pesticides, etc. are all suspected carcinogens.

(4) Some drinking water is often contaminated by polychlorinated biphenyls, chloroform, etc. In recent years, it has been found that blue-green algae growing in ponds are strong carcinogenic plants that can pollute water sources. Parasitic diseases such as Clonorchis sinensis infection can stimulate bile duct epithelial hyperplasia and lead to primary bile duct cancer.

(5) Long-term alcohol abuse is the number one killer of the liver. This is because after alcohol enters the human body, it is mainly metabolized in the liver. The toxicity of alcohol to liver cells causes liver cells to have problems with the decomposition and metabolism of fatty acids, causing fat deposition in the liver and resulting in fatty liver.

The above are the causes of liver cancer. I hope everyone will pay attention to it.
