What are the causes of liver cancer?

Liver cancer is the third most common malignant tumor with a mortality rate second only to gastric cancer and esophageal cancer. The early symptoms are not obvious, and the late stage mainly manifests as liver pain, fatigue, weight loss, jaundice, ascites and other symptoms. So what are the factors that cause liver cancer? According to research reports: The main causes of liver cancer in my country are viral hepatitis infection, aflatoxin contamination in food, and drinking water pollution in rural areas. The following is a detailed analysis of 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 more alcohol you drink, the more severe the fatty liver becomes. It can also induce liver fibrosis and then cause cirrhosis. Secondly, eating moldy peanuts, corn, and fried dough sticks cooked with gutter oil can also increase the incidence of liver cancer by 33% to 66%.

The above is the cause of liver cancer. I believe you must have understood it. Since the early symptoms of liver cancer are not obvious, but the cure rate of patients in the late stage is low due to the spread of cancer cells, it is necessary to achieve early detection, early diagnosis, and early treatment of liver cancer. Do a good job in liver cancer prevention and adhere to the seven-character liver cancer prevention policy of "managing water, managing food, and preventing hepatitis".
