Causes of primary liver cancer

Liver cancer includes primary liver cancer and metastatic liver cancer. When people talk about liver cancer, they are mostly referring to primary liver cancer. At present, the cause of primary liver cancer has not been fully elucidated, but according to epidemiological surveys in high-incidence areas, it is closely related to the following factors. Prevention of liver cancer should also start from the source, try to do regular check-ups, drink less alcohol, and pay attention to food hygiene.

1. Viral hepatitis: This includes hepatitis B and C. The cause is speculated to be the hepatitis virus causing liver cell damage followed by hyperplasia or atypical hyperplasia, which makes it sensitive to carcinogens. In the process of multiple causes and stages of the disease, multiple genes may change, resulting in uncontrolled cell growth, continuous proliferation of liver cells, and finally cancer.

2. Alcohol: In Western countries, drinking is the main factor in the etiology of chronic liver disease, but studies have shown that alcohol has no direct relationship with liver cancer cells. It acts like a catalyst and can promote the occurrence and progression of liver cancer. This is because alcohol affects the normal metabolism of the liver, causing fat deposition in the liver and resulting in fatty liver. The more you drink,

3. Diet: Long-term consumption of moldy food, food containing nitrosamines, and lack of trace element arsenic are important factors that promote liver cancer. Among them, aflatoxin in moldy food and nitrite in pickled food are the main carcinogens.

4. Other factors: such as drinking water pollution, genetic factors, parasitic infection, etc.
