What are the causative factors of liver cancer? The formation of liver cancer is related to three factors

China is a country with a high incidence of hepatitis B. Most liver cancers in my country develop from hepatitis B cirrhosis, which will then develop into liver cancer. At present, the number of cases in my country accounts for more than half of the world's cases, and 55% of the world's liver cancer patients. It has become a major killer that seriously threatens the health and lives of the Chinese people. Its danger should not be underestimated. So what are the common causes of liver cancer? Let's listen to what the experts say.

In general, the cause of liver cancer has not been fully elucidated so far, but it has been shown to be closely related to the following factors:

1. Viral hepatitis: Epidemiological statistics show that areas where hepatitis B is prevalent are also high-incidence areas for liver cancer. People who have had hepatitis B are 10 times more likely to develop liver cancer than those who have not. Long-term clinical observations have found that hepatitis, cirrhosis, and liver cancer are a trilogy of continuous migration and evolution. Recent studies have shown that viral hepatitis related to liver cancer mainly includes hepatitis B (HBV) and hepatitis C (BCV), among which hepatitis B is the most common.

2. Alcohol: As the saying goes, "drinking alcohol hurts the liver." Alcohol is not the direct cause of liver cancer, but it acts like a catalyst and can promote the occurrence and progression of liver cancer. People with a long-term alcohol addiction are prone to liver cancer. This is because after alcohol enters the human body, it is mainly decomposed and metabolized in the liver. The toxicity of alcohol to liver cells causes liver cells to have obstacles in the decomposition and metabolism of fatty acids, causing fat deposition in the liver and causing fatty liver. The more alcohol is consumed, the more severe the fatty liver is, which in turn causes liver fibrosis, cirrhosis, and liver cancer. If hepatitis patients drink a lot of alcohol, it will greatly accelerate and aggravate the formation and development of cirrhosis and promote the occurrence of liver cancer.

3. Diet-related factors: The occurrence of liver cancer is closely related to lifestyle habits. Long-term consumption of moldy food, food containing nitrosamines, and lack of trace element selenium are also important factors that promote liver cancer. Aflatoxin B1 is a substance that has been proven to have a clear carcinogenic effect. It mainly exists in moldy food, such as corn, peanuts, rice, etc. In addition, when a large amount of food containing nitrite is consumed, nitrite accumulates in the body and cannot be discharged in time, and can be converted into nitrosamines in the body. Foods with high nitrite content are smoked or salted meat products, which have a clear carcinogenic effect. At the same time, the occurrence of liver cancer is also related to genetic factors, parasitic infections and other factors.
