The "invisible killer" of liver cancer? These 3 are

Liver cancer is a terrible liver disease. In clinical trials, liver cancer often occurs in certain populations. Why are these high-risk groups prone to liver cancer? What are the "invisible killers" that cause liver cancer?

1. Aflatoxin

Clinical experiments have found that some liver cancer patients have no history of hepatitis B or C virus infection, nor do they have underlying liver diseases such as cirrhosis. Tracing the cause, it was found that these people had long-term and large-scale exposure to carcinogens, the most critical of which was aflatoxin.

Animal experiments have confirmed that there are more than ten metabolites of aflatoxin. Aflatoxin Bl is the most common one and is directly related to liver cancer. Aflatoxin Bl is a highly toxic substance. It has a strong carcinogenic effect, which is 75 times stronger than N-nitrosodimethylamine. It can induce liver cancer in all animals. Aflatoxin exists in moldy peanuts, corn, etc. Therefore, not eating moldy peanuts, corn, and foods such as fried dough sticks and cakes fried in gutter oil can effectively reduce the incidence of liver cancer.

2. Drinking water

In recent years, as environmental pollution has become more serious, the eutrophication of some water bodies has become increasingly obvious. The reproduction rate of various algae has greatly increased. The green blue algae growing in pond water is a strong carcinogenic plant. Microcystin is a strong carcinogen with considerable toxicity. An epidemiological survey of drinking water confirmed that people who drank pond water seriously polluted by green algae had high incidence and mortality rates of liver cancer. Therefore, paying attention to drinking water hygiene is also an effective way to prevent liver cancer.

3. Tobacco and alcohol

Excessive drinking is another major cause of liver damage. There is a clear positive correlation between alcohol intake and the incidence of liver cancer. The longer you drink, the greater the chance of liver cancer. In recent years, some studies have found that cocaine, nicotine, nitrosamines and other substances in cigarettes are carcinogens. In addition to causing direct damage to liver cells, if combined with other pathogenic factors, it will cause further damage to the liver and induce liver cancer.
