Which chemical carcinogens cause liver cancer? Which fruits are suitable for preventing liver cancer?

As more and more people suffer from liver cancer, liver cancer has gradually been taken seriously. Liver cancer poses a great threat to our health and well-being, and even threatens the life safety of patients. Young people around 40 years old are in the best years of their lives, but unfortunately many of them suffer from liver cancer. So, what are the causes of liver cancer? Studies have shown that the occurrence of liver cancer in my country is mainly related to hepatitis B and C virus infection, aflatoxin, drinking water pollution, etc. Some pesticides, liver flukes, genetics, addiction, etc. may also be related to the onset of liver cancer.

Check out the top ten causes of liver cancer

1. Viral hepatitis

It is now known that hepatitis B is closely related to liver cancer, followed by hepatitis C which has been confirmed in recent years. The HBsAg positivity rate in liver cancer cases can be as high as 81.82%. Foreign reports show that 60% to 90% of liver cancers in areas with a high incidence of liver cancer are caused by HBV. In recent years, it has been reported that in HBV-positive liver cancer patients, HBV genes can be seen integrated into the DNA of liver cancer cells. Therefore, HBV is considered an important factor in the occurrence of liver cancer. Recently, HCV infection has also been considered to be one of the possible pathogenic factors of liver cancer. It is reported that 70% of liver cancer patients in Japan and 65% to 75% in Western Europe are found to be HCV antibody positive.

2. Cirrhosis

There is a close relationship between cirrhosis and liver cancer. According to statistics, it usually takes about 7 years for cirrhosis to develop into liver cancer. Among them, post-necrotic cirrhosis is the most common, followed by post-hepatitis cirrhosis, and portal cirrhosis is the least common.

3. Fungi

Fungi and their toxins, such as Aspergillus flavus, Penicillium, and Aspergillus versicolor, can all cause experimental liver cancer. Among them, Aspergillus flavus is the most important. The use of this fungus or its toxins (aflatoxin), or food contaminated by it, can induce liver cancer in animals. In areas with a high incidence of liver cancer, food contamination by Aspergillus flavus is often more serious.

4. Nitrosamine compounds

Dimethylnitrosamine has been isolated from the food of South Africans, a region with a high incidence of liver cancer. Such compounds can also cause other tumors such as esophageal cancer.

5. Viral infection

Recent data show that the HBsAg positivity rate of liver cancer patients in developing countries is greater than 50%, while the anti-HCV positivity rate of liver cancer patients in developed countries is mostly higher than 50%. Therefore, it is speculated that HBV infection may be the main cause of liver cancer in developing countries, while hepatitis C virus is the main cause of liver cancer in developed countries.

6. Chemical carcinogens

Aflatoxin B1 is a highly toxic substance, 900 times more carcinogenic than butter, and can induce liver cancer in all animals. Others such as vinyl chloride, thorium dioxide, diethylnitrosamine, etc. are also carcinogenic to a certain extent.

7. Alcoholism

Alcohol poisoning can cause alcoholic fatty liver, alcoholic hepatitis, and alcoholic cirrhosis. In alcoholic hepatitis or cirrhosis, the number of Kupffer cells decreases, which can increase the occurrence of liver cell cancer.

8. Trace elements

Low levels of selenium, molybdenum, manganese, zinc, and high levels of iron, arsenic, nickel, etc. may be related to the occurrence of liver cancer.

9. Medication

Certain drugs have a cumulative effect and can cause cancer.

10. Drinking water pollution

Studies have shown that the occurrence of liver cancer is closely related to drinking water pollution. More than 100 organic substances have been found to be carcinogenic, cancer-promoting and mutagenic, such as hexachlorobenzene, benzopyrene, polychlorinated biphenyls, chloroform, ethylene dibromide, dichloroethylene, vinyl chloride, benzofluoranthene, tetrachloromethane, indenopyrene, etc. In addition, heredity also plays a role in the occurrence of primary liver cancer.

How to prevent liver cancer in daily life

1. Treatment of hepatitis. Many patients have various forms of hepatitis before they develop liver cancer. The most common are hepatitis B and hepatitis C. If they are not treated for a long time, it will lead to liver fibrosis and cirrhosis, and eventually cause liver cancer. Therefore, you must pay attention to preventing hepatitis and get vaccinated in time.

2. Do not eat moldy food. The most common cause of liver cancer is aflatoxin, a chemical that exists in large quantities in moldy food and is a highly carcinogenic substance. If you eat some moldy vegetables and food for a long time, it will greatly increase the incidence of liver cancer.

3. Quit smoking and drinking in time. Tobacco and alcohol contain carcinogens - nitrite. It is easy to have the habit of excessive drinking and smoking. It must be corrected in time to prevent the occurrence of cancer. If you drink alcohol for a long time, it is very likely to cause alcoholic hepatitis, which will cause the normal function of the liver to be disturbed, and in the long run, it will cause cirrhosis and liver cancer.

4. Do not use drugs recklessly. All drugs are toxic. Do not use drugs recklessly. Many drugs are detoxified by the liver. Once the toxicity of the drugs accumulates, it will cause damage to the liver, increase the burden on the liver, and aggravate the condition.

5. Take a rest in time and avoid long-term fatigue. Make sure you get enough rest every day and avoid overwork, which can easily lead to a decrease in your body's immunity and make you vulnerable to viruses. In addition, you should maintain a positive attitude and a cheerful mood.

6. Regular physical examinations. Regular physical examinations should be conducted every year, especially for hepatitis patients and people over 35 years old. Once you feel unwell, you should get checked and treated in time to prevent the onset of liver cancer.

Which fruits are suitable for preventing liver cancer?

1. Banana

Bananas are rich in protein, sugar, vitamins, magnesium and potassium. They can promote liver cell regeneration, improve immunity, and prevent and fight cancer. They are especially suitable for liver cancer patients who suffer from blood heat, dry mouth and throat, and dry stools after radiotherapy.

2. Apple

Apples are rich in vitamin C and natural chemical antioxidants such as polyphenols and flavonoids. They have the effects of promoting fluid production and quenching thirst, moistening the lungs and relieving restlessness, strengthening the spleen and stomach, nourishing the heart and invigorating qi, and preventing and fighting cancer. They are known as "the doctor's first medicine."

3. Kiwi

Kiwi fruit is rich in vitamin C, ranking first among fruits. It has the effects of clearing away heat, promoting body fluid, promoting blood circulation and promoting water circulation. It can also protect the interstitial barrier and eliminate ingested carcinogens, which can prolong the life of cancer patients to a certain extent. It is especially suitable for cancer patients to eat after radiotherapy and chemotherapy.

4. Figs

Figs contain a large amount of inorganic elements that are beneficial to the human body and can enhance the body's anti-cancer ability; the dietary fiber they contain (especially pectin and hemicellulose) can absorb a variety of chemicals after swelling with water, thereby purifying the intestines and eliminating carcinogens.

5. Red dates

Red dates are rich in vitamin C, cAMp, triterpenoid compounds, etc., which have the effects of tonifying deficiency and replenishing Qi, nourishing blood and calming the nerves, strengthening the spleen and stomach, etc. They can participate in cell division and differentiation, morphogenesis, inhibit cancer cell reproduction, promote growth and development, enhance physical strength, reduce fatigue, etc. It is especially suitable for liver cancer patients with weak spleen and stomach, insufficient Qi and blood, fatigue, weakness, insomnia and dreaminess.

6. Grapes

Grapes contain minerals such as calcium, potassium, phosphorus, iron, and multiple vitamins, which can fully replenish the body's energy. The resveratrol they contain can prevent normal cells from becoming cancerous, inhibit the spread of malignant cells, etc. It has the effects of invigorating qi and blood, relieving restlessness and thirst, and strengthening the stomach and promoting urination. It is especially suitable for liver cancer patients after radiotherapy, chemotherapy and surgery.

7. Strawberries

The ellagic acid in strawberries can protect the body from carcinogens and has a certain anti-cancer effect. It also has the effect of promoting salivation and quenching thirst, relieving throat and moistening the lungs. It can relieve symptoms such as dry mouth and throat in liver cancer patients after radiotherapy and chemotherapy.
