Introduction to several common causes of liver cancer

Liver cancer is one of the most common malignant tumors, and many people have lost their precious lives due to liver cancer. What are the causes of liver cancer ? Here are some common causes of liver cancer.

In general, the common causes of liver cancer are:

1. Viral hepatitis: It is one of the common causes of liver cancer. Generally speaking, hepatitis B and hepatitis C are closely related to the cause of liver cancer. The HBsAg positive rate in liver cancer cases can be as high as 81.82%. It is reported that in HBV-positive liver cancer patients, HBV genes can be seen integrated into the DNA of liver cancer cells, so HBV is considered an important cause of liver cancer.

2. Liver cirrhosis: There is a close relationship between liver cirrhosis and the cause of liver cancer. According to statistics, it usually takes about 7 years for liver 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 and their toxins: Aspergillus flavus, Penicillium, Aspergillus versicolor, etc. may be the cause of liver cancer, among which Aspergillus flavus is the most important. Studies have found that aflatoxin B1 is a highly toxic substance, which is 900 times more carcinogenic than butter. It can induce liver cancer in all animals and is also considered a common cause of liver cancer. A large number of scientific experiments have proved that feeding experimental animals with foods containing Aspergillus flavus or its toxins can cause liver cancer in animals. Foods that are prone to mold include rice, wheat, soybeans, peanuts, and corn.

4. Nitrosamine compounds: Dimethylnitrosamine has been isolated from the food of residents in South Africa, a high-risk area for liver cancer. Such compounds can also cause other tumors such as esophageal cancer, so nitrosamine compounds are also classified as the cause of liver cancer.
