What are the causes of liver cancer? 8 causes of liver cancer known early

In many countries around the world, including Southeast Asia and sub-Saharan Africa, 80% of liver cancer cases are caused by exposure to the fungus aflatoxin. This fungus is commonly found in corn, peanuts, and other crops and is a staple food in these regions. Now, researchers from MIT have developed a method to sequence the DNA of stem cells to see if these cells have been affected by aflatoxin. This mutation profile could help researchers identify people at risk for liver cancer, potentially predicting it years before a tumor forms.

What are the causes of liver cancer?

Liver cancer is a common malignant tumor with a very high mortality rate. The cause of liver cancer has always been a key topic of concern. So what are the causes of liver cancer?

1. Chronic liver disease: viral hepatitis, in particular, is closely related to the onset of liver cancer and is called the "catalyst" of liver cancer by the medical community. Hepatitis B (HBV) and hepatitis C (HCV) are the most important. Data show that more than 30% of liver cancer patients have a history of chronic hepatitis, and more than half of them are positive for Australia antibody (HbsAg). Therefore, hepatitis B virus and hepatitis C virus are regarded as one of the cancer-promoting factors, which is the cause of liver cancer.

2. Long-term consumption of pickled, fried, smoked and grilled foods can also induce liver cancer: nitrosamines contained in pickled foods and 3,4-benzopyrene contained in fried and smoked foods can induce cancer, so everyone should try to reduce the consumption of pickled, fried, smoked and grilled foods such as pickled meat, grilled meat, grilled sausages, salted fish, pickles, etc. in daily life. 3. Cirrhosis: Medical observations have found that about 50% to 90% of liver cancer patients have varying degrees of liver cirrhosis, so liver cirrhosis is also considered a cancer-promoting factor. Therefore, patients with liver cirrhosis should do regular checkups to prevent the occurrence of liver cancer.

4. Eating spoiled food can also induce liver cancer: Studies have found that moldy food will produce a toxic metabolite in its mold - aflatoxin, which is the strongest biological carcinogen discovered today. Therefore, people should avoid eating moldy foods such as moldy peanuts, corn, rice, dried potatoes, dried radishes, dairy products, and soy products.

5. Water pollution: Severe pollution of drinking water is one of the important causes of liver cancer, especially polluted ditch water, followed by river water, and well water is the lowest. Therefore, in villages without tap water facilities, drinking well water should be encouraged.

6. Immune status: Some people believe that the plasma of liver cancer patients contains a blocking factor that can inhibit cellular immunity and protect liver cancer cells from being killed by immune cells. It has been proven that alpha-fetoprotein (AFp) can inhibit the phagocytosis of lymphocytes and macrophages.

7. Gene mutation: In recent years, some people believe that mutagens and viruses in the environment stimulate the activation of liver cell division response pathways, causing point mutations and gene translocations in cells, which are possible factors that accelerate the proliferation of cancer cells.

8. Other factors: Overnutrition (macronutrients) or nutritional deficiency (such as vitamin A, B1 deficiency), hemochromatosis, parasitic infection and heredity are also risk factors for liver cancer.

If you have liver cancer, the first thing you will feel is fatigue. Even if you lie down and rest, you will not be able to get rid of the fatigue. This kind of fatigue and tiredness that cannot be eliminated is a common symptom of liver disease. The heat energy generated by the food consumed by the human body will be absorbed by the intestines, and part of it will be transported to the liver, where it will be stored and then transported to cells throughout the body. If the liver is invaded by cancer cells, the fuel supply of the whole body will be reduced. As a result, the body will become tired and easily fatigued due to insufficient heat energy. If you are just tired or lazy, it may also be due to a cold or excessive fatigue. Few people realize that they may have liver cancer, so the disease is delayed.
