What is the cause of liver cancer? 6 ways to quickly help you prevent liver cancer

None of us want to get liver cancer because it will cause us great pain. Do you know how to prevent liver cancer?

The incidence of liver cancer in my country ranks first in the world. Among all cancers, liver cancer ranks second in mortality (after gastric cancer). Moreover, most liver cancer cases are discovered late, and the treatment cost is high and the effect is poor. Therefore, early prevention of liver cancer is particularly important. Liver cancer is the result of the synergistic effect of multiple factors, and its occurrence is multi-stage. Therefore, the prevention of liver cancer is to take corresponding measures against its biological, chemical and other factors to curb its occurrence and development.

Main measures to prevent liver cancer

1. Get the hepatitis B vaccine: The World Health Organization (WHO) pointed out at a liver cancer prevention conference that the correlation between hepatitis B virus and liver cancer is as high as 80%. Hepatitis B virus is second only to tobacco and is the second known carcinogenic factor in humans. Therefore, the hepatitis B vaccine is considered the first vaccine against liver cancer. Therefore, the hepatitis B vaccine is an important measure to prevent liver cancer.

2. Control hepatitis C: Among liver cancer patients with negative hepatitis B surface antigen in my country, 28.5% are positive for anti-hepatitis C virus, which shows that hepatitis C virus is also an important carcinogenic factor. It is found from current clinical patients that 80% to 90% of hepatitis C is transmitted through blood and blood products. Therefore, strictly controlling the source of blood transfusion and minimizing blood transfusion or the use of blood products are effective measures to reduce hepatitis C and control the occurrence of liver cancer.

3. Avoid eating moldy food: Aflatoxin is a highly toxic substance, which is 75 times more carcinogenic than dimethylnitrosamine. It can induce liver cancer in all animals. The International Agency for Research on Cancer has listed aflatoxin B1 as a human carcinogen. Aflatoxin B1 is also one of the factors that trigger liver cancer. Therefore, refuse to eat moldy or suspected moldy food, especially moldy corn and peanuts.

4. Appropriate selenium supplementation: People with low selenium levels can eat more selenium-containing yeast, selenium polysaccharides, selenium-rich salt and other foods to supplement selenium, increase the selenium content in the human body, and effectively prevent the occurrence of liver cancer.

5. Others: Preventing water pollution, paying attention to hygiene, improving nutrition, combining work and rest, enhancing immune function, eliminating drug abuse and abandoning bad habits can also effectively prevent the occurrence of liver cancer.

6. Improve the awareness of liver cancer: Patients with hepatitis B or C should receive prompt and thorough treatment to prevent the occurrence of liver cirrhosis. Some hepatitis patients and those with a family history of liver cancer should insist on having a comprehensive liver examination once a year, including an alpha-fetoprotein test, so as to detect cancer in time. A large number of studies have shown that the success rate of liver cancer surgery with a diameter of less than 3 cm is 90%, and the five-year survival rate after surgery can reach more than 85%, and some patients can even survive for a long time.

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 a small number of patients with this disease have a history of chronic hepatitis, and more than half of them are positive for Australia anti-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, and smoked foods can also induce liver cancer: The nitrosamines contained in pickled foods and the 3,4-benzopyrene contained in fried and smoked foods can induce cancer, so in daily life, we should try to reduce the consumption of pickled meat, grilled meat, grilled sausages, salted fish, pickles and other pickled, fried, and smoked foods.

3. Cirrhosis: Medical observations have found that most patients with liver cancer have varying degrees of cirrhosis, so cirrhosis is also considered a cancer-promoting factor. Therefore, patients with cirrhosis should undergo 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 - aflatoxin in its mold, and aflatoxin 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, soy products, etc.

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 liver 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. (Reference website: Seeking Medical Network)
