Do you know why liver cancer occurs? 5 foods that can cause liver cancer

Liver cancer refers to a malignant tumor that occurs in liver cells or intrahepatic bile duct epithelial cells. Do you know which foods you eat daily are most likely to cause liver cancer?

Some people usually have no symptoms, can eat and sleep well, but when they are checked, they are found to have advanced liver cancer. Do you know why liver cancer occurs? In fact, it is because of the foods you usually eat.

5 foods that 100% cause liver cancer

1. Moldy food

Aflatoxin in fungi is a carcinogen that can induce liver cancer in humans, monkeys, mice, and poultry. The shortest time required for cancer is 24 weeks. To prevent fungal contamination of food, pay attention to the fact that peanuts, corn, sweet potato chips, rice, millet, etc. stored at home must be dried thoroughly and stored in a dry and ventilated environment; moldy peanuts, potato chips, radish chips, etc. should be discarded and cannot be eaten by humans, livestock, and poultry; peanut oil and cottonseed oil should not be stored for a long time; when a large number of grain, oil, and dairy products are suspected of fungal contamination, the quarantine station should be asked to check and only after approval can they be distributed, sold, or eaten.

2. Deteriorated animal and vegetable oils

Stale oils all contain malondialdehyde, a chemical component that can generate polymers and react with proteins and DNA in the human body, causing the protein structure to mutate, causing cells with mutated proteins to lose their normal functions and transform into early cancer cells. In addition, malondialdehyde polymers can hinder the replication of DNA and accelerate the aging process of people. Therefore, animal and vegetable oils should not be stored for too long, and oils that have deteriorated and have a rancid smell should not be eaten. Foods fried with rancid oil not only taste bad, but more importantly, they can cause cancer and shorten people's lifespan.

3. Pickled, fried, smoked and grilled food

Such as pickled meat, grilled meat, grilled sausage, salted fish, pickled vegetables, etc., which is also one of the common causes of 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 meat, salted fish, grilled meat, grilled sausage and pickled vegetables as much as possible in daily life.

4. Wine

Long-term, heavy drinking will seriously damage liver health, thus leading to liver cancer. The degree of damage caused by alcoholic liver disease is closely related to the daily amount of alcohol consumed, the time of drinking, and the way of drinking. Alcohol needs to be metabolized by the liver in the human body, and the acetaldehyde produced by metabolism is extremely toxic to the human body. Long-term heavy drinking can lead to cell damage, fat deposition in liver cells, inflammation and necrosis of liver cells, and hyperplasia of fibrous connective tissue, which can eventually lead to cirrhosis of the liver, and some cirrhosis of the liver will turn into liver cancer.

5. Polluted water sources

As environmental pollution becomes increasingly serious, water pollution has also become one of the factors causing liver cancer. Severe pollution of drinking water quality is an important cause 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 advocated. According to research, more than 100 kinds of organic substances have been found to be carcinogenic, cancer-promoting and mutagenic: such as hexachlorobenzene, benzopyrene, polychlorinated biphenyls, chloroform, dibromoethane, dichloroethylene, vinyl chloride, benzofluoranthene, tetrachloromethane, indenopyrene, etc. Therefore, if they are exposed to more in daily life, they may lead to cancer.

Eight early symptoms of liver cancer

1. Digestive system symptoms

Loss of appetite, nausea, vomiting, diarrhea, and diarrhea are mostly undigested food residues; in addition, digestive tract dysfunction, enlarged tumor compression and involvement of the stomach can lead to portal hypertension. Impaired liver function and decreased digestion and absorption function can cause patients to lose weight for unknown reasons, which is also a common symptom of liver cancer patients.

2. Pain in the liver area

Clinically, the first symptom of liver cancer patients is mostly pain in the liver area, especially those with a history of hepatitis and cirrhosis. It is usually located in the right rib or under the xiphoid process, and is usually intermittent or persistent dull pain, dull pain or stabbing pain. Early patients will feel discomfort in the right upper abdomen, which may be mild or severe or relieved by itself in the short term. Most of them are dull pain and distending pain. Due to the rapid growth of the tumor, the liver capsule becomes tense and swollen. If the pain is severe and stabbing, radiating to the back, right shoulder and waist, and acute abdomen suddenly occurs in the liver area, it may be a rupture of liver cancer;

3. Abdominal distension

It is caused by huge tumor, ascites and liver dysfunction; abdominal distension is obvious in the upper abdomen, especially after meals and in the afternoon, and the distension is aggravated.

4. Upper abdominal mass

It often manifests as a mass under the xiphoid process of the left liver and a mass under the ribs of the right liver. The lumps are mostly painless, with uneven nodules and a hard texture when touched. Adults over 30 years old usually feel a mass in the right upper abdomen and upper abdomen. The mass is hard in texture, has an uneven surface, and has an obvious tendency to continue to grow.

5. Fatigue and weight loss

Caused by the metabolites of malignant tumors and lack of food intake, cachexia occurs in the late stage

6. Fever

It can be caused by tumor necrosis, concurrent infection, and tumor metabolites. Irregular fever: Tumor patients are prone to concurrent infection due to low resistance. Some liver cancer patients will have unexplained fever, generally around 37.5℃～38℃, sometimes reaching above 39℃, mostly irregular fever, not accompanied by chills, afternoon fever is more common, and sometimes remittent fever can also be seen. Fever is caused by the release of pyrogens into the blood circulation after tumor tissue necrosis.

7. Jaundice

This is a late stage manifestation and can also be caused by bile duct tumor thrombus. In addition to tumor compression of the bile duct, late stage patients may also have hepatocellular jaundice.

8. Other symptoms

Such as bleeding tendency, edema of both lower limbs, itchy skin, etc. Due to impaired liver function and abnormal coagulation function, liver cancer patients often experience symptoms such as bleeding gums and subcutaneous ecchymosis, which are more common in patients with liver cancer and cirrhosis. Gastrointestinal bleeding is also common, mainly due to portal hypertension leading to esophageal varices. Gastrointestinal bleeding is also one of the main causes of death in liver cancer patients.
