Seven factors that cause liver cancer

At present, people are paying more and more attention to the causes of liver cancer, and have invested a lot of energy in research, in order to do a good job of prevention in time and reduce the incidence rate. So, the following is an introduction by experts on the factors that cause liver cancer .

1. 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.

2. Viral hepatitis:

Mainly due to hepatitis B and C virus infection, especially hepatitis B and hepatitis B virus carriers, the incidence of primary liver cancer is 2 to 100 times higher than that of normal people; in areas with high incidence of liver cancer, about 20% of people may be hepatitis B or hepatitis B virus carriers. This is one of the factors that cause liver cancer.

3. Aflatoxin (AFT):

Aflatoxin B is the most important carcinogen. It is suitable for growing and reproducing in high temperature and high humidity climates, especially in summer, when moldy food, grains, and feed are most likely to be contaminated by Aspergillus flavus and produce aflatoxin. Long-term consumption of food containing this toxin can induce liver cancer.

4. Chemical carcinogens: Chemical substances that can cause liver cancer are mainly N-nitroso compounds, such as nitrosamines and nitrosamides, etc. In addition, pesticides, alcohol, safrole, etc. can also induce liver cancer.

5. Gene mutation:

Others 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.

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. Studies have shown that alpha-fetoprotein (AFP) can inhibit the phagocytosis of lymphocytes and macrophages.

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

The above is an introduction to the factors that cause liver cancer. Prevention of liver cancer starts with each of us. If you want to know more about liver cancer, please consult online experts.
