In our lives, there are many negative factors that constantly trouble us, many of which can lead to liver cancer. Through continuous research by medical personnel, it is found that water pollution, viral hepatitis, chemicals, and gene mutations are the main factors that lead to liver cancer. Here is an explanation of the causes of liver cancer. 1. Causes of liver cancer: The etiology and exact molecular mechanism of primary liver cancer are not yet fully understood. It is currently believed that its onset is a complex process with multiple factors and steps, which is affected by both environmental and environmental factors. Epidemiological and experimental research data show that hepatitis B virus (HBV) and hepatitis C virus (HCV) infection, aflatoxin, drinking water pollution, alcohol, cirrhosis, sex hormones, nitrosamines, trace elements, etc. are all related to the onset of liver cancer. Secondary liver cancer (metastatic liver cancer) can form diseases through different pathways, such as metastasis with blood and lymph or direct invasion of the liver. In short, the incidence of liver cancer is high, and the pathogenesis is still unknown. Hepatitis B, C, cirrhosis, liver cell necrosis accompanied by liver cell regeneration are prone to malignant transformation. Secondly, various carcinogens may be related to the onset of the disease, such as aflatoxin B2, a metabolite of Aspergillus flavus, which has a strong carcinogenic effect, and some organic carcinogens, chemicals or algae toxins that pollute water sources can also cause cancer. 2. Populations with a high risk of liver cancer 1. Hepatitis patients or carriers, especially those with a history of more than 5 years or those over 40 years old. 2. Liver cirrhosis. Liver cancer often occurs on the basis of liver cirrhosis. 3. People with bad eating habits: smoking, drinking, and long-term consumption of pickled, smoked, moldy and other foods. 4. There is a confirmed liver cancer patient in the family, especially a first-degree relative. 5. Those who suffer from long-term work pressure, heavy workload or long-term mental depression. Although liver cancer can occur in all age groups, it is relatively rare in children. Usually, the median age of liver cancer is low in high-incidence areas, and higher in low-incidence areas. In my country, the incidence population is mostly concentrated in the age group of 45 to 65, but clinical studies in recent years have found that the incidence rate among young people has a significant upward trend compared with the past. Liver cancer is more common in men, and the male to female ratio of liver cancer in my country is about 3:1. When residents in high-incidence areas move to low-incidence areas, the mortality rate of liver cancer also decreases. The above is a summary of the causes of liver cancer and the high-risk population for liver cancer. I hope it will be helpful to you. For many patients, the occurrence of this disease is mainly inseparable from their own living and eating habits. If you develop good living habits, do these things well at ordinary times, stay away from pollution sources, and stay away from virus troubles, you can prevent the occurrence of many diseases. |
