China is a high incidence area of liver cancer, about 110,000 people die from liver cancer every year, people can’t help but ask what causes liver cancer? What are the details to pay attention to in daily life?
What is liver cancer? Liver cancer refers to malignant tumors occurring in the liver, including primary liver cancer and metastatic liver cancer, which are mostly referred to as primary liver cancer. The etiology and exact molecular mechanism of primary liver cancer are still not fully understood, and it is believed that its development is a multifactorial and multi-step complex process influenced by environmental and other factors. So what predisposing factors can lead to the development of the disease?
1, hepatitis B virus (HBV) and hepatitis C virus (HCV) infection.
In the family of hepatitis viruses, the second oldest hepatitis B virus (HBV) and the third oldest hepatitis C virus (HCV) play a huge role in the development and growth of the family. Let’s analyze their molecular mechanisms below. It was found that HBV may integrate its DNA into human hepatocyte DNA, which in turn promotes stem cell carcinogenesis. HCV core protein has an oncogenic effect in vitro, and the core protein can regulate gene transcription and the proliferation and apoptosis of host cells.
2. Aflatoxin.
It is a kind of mold in inducing carcinogenesis, and its toxin B1 will have strong toxic effects on the liver. After the food containing toxin is ingested and absorbed by the liver, it can cause degeneration and necrosis of liver cells, and then induce liver cancer. A lot of studies have proved that the intake of aflatoxin B1 is directly proportional to the mortality rate of liver cancer.
3.Drinking water pollution.
One of the functions of liver is to process and filter blood, and polluted water will make the quality of blood lower, and the long-term accumulation of harmful substances in human cells and blood will cause damage to cell tissues, forming hepatitis and cirrhosis, and even triggering cancer. Therefore, polluted water is also one of the main reasons for the formation of liver disease.
4.Drinking alcohol.
One of the main culprits of liver cancer in China is alcohol consumption, and many patients’ liver cancer is “drunk” out. Alcohol relies on the liver to metabolize, and the metabolic process will produce toxic substances that cannot be completely removed by the body itself, such as oxidants, superoxide and other substances. Excessive alcohol abuse can destroy liver cells and lead to cirrhosis of the liver, which eventually leads to liver cancer.
5.Other.
Viral hepatitis, liver cirrhosis and other factors.
As the saying goes, prevention is better than cure. In the face of liver cancer, we can only start from the details of life, so that liver cancer can be rejected by us. We can try to do the following things.
1. Refuse to eat moldy food.
Moldy food contains a lot of aflatoxin, especially peanuts, corn, soybeans and sweet potatoes, which can no longer be consumed.
2, eat less pickled food.
People in some areas of China love to eat pickles, but experiments have proved that pickles contain high amounts of nitrosamines, such as pickles, sauerkraut, cured meat, etc. These pickles, although refreshing and appetizing, are associated with the occurrence of liver cancer, and frequent consumption of these foods will easily cause cancer.
3. Reduce the intake of wine.
Alcohol can make cancer cells grow and cause carcinogenic substances to penetrate into cell membranes. Cancer tends to favor those who drink excessively, therefore, alcohol drinkers should drink in moderation.
4. Eat more fresh fruits and vegetables.
Fresh fruits contain natural pigments, which can effectively prevent cancer. Some fruits contain beta carotene, which is converted into vitamin A in human body and can prevent cells from free radical damage. There are also anti-cancer substances in citrus fruits, which can help convert fat-soluble carcinogens into water-soluble ones and facilitate their discharge from the body.
5.Keep your mood relaxed.
When you are driven by negative emotions all day long and suppressed for a long time, various diseases will often come to your door, and even cancer will follow, so it is important to keep a good mood.
Liver cancer is very scary, but as long as you pay attention to these “small details” in life, liver cancer is not so easy to happen, we expect to be healthy, so having a healthy body is more important than anything else.
