What are the causes of liver cancer? Analysis of 7 causes of liver cancer

When it comes to liver cancer, I believe that anyone who knows a little about it will be terrified. In fact, this is understandable. After all, liver cancer is a very terrible disease, and sometimes it can even cause death. What is more noteworthy is that the incidence of liver cancer has been increasing year by year, causing great harm to many patients. What are the causes of liver cancer? Let's take a look. (1) Viral hepatitis: mainly hepatitis B and C virus infection, especially hepatitis B and hepatitis B virus carriers, whose incidence of primary liver cancer is 2 to 100 times higher than that of normal people; in areas with a high incidence of liver cancer, about 20% of people may be hepatitis B or hepatitis B virus carriers. (2) Aflatoxin (AFT): Aflatoxin B is the most important carcinogen. It is suitable for growth and reproduction in a high temperature and high humidity climate environment, especially moldy food, grains, feed, etc. in summer, which are most likely to be contaminated by Aspergillus flavus and produce aflatoxin. Long-term consumption of food containing this toxin can induce liver cancer. (3) 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. (4) Chemical carcinogens: Chemical substances that can cause liver cancer are mainly N-nitroso compounds, such as nitrosamines and nitrosamides. In addition, pesticides, alcohol, safrole, etc. can also induce liver cancer. (5) Other 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. (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 reaction pathways, causing cell point mutations and gene translocations, which are possible factors that accelerate the proliferation of cancer cells. The above is an introduction to the causes of liver cancer. I hope it can increase everyone's vigilance against this disease. Liver cancer is a high-incidence disease in my country. 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. Everyone really needs to take relevant prevention and control measures. Finally, I wish you all good health.
