What are the main causes of liver cancer? 3 specific causes of liver cancer

1. The viral hepatitis associated with liver cancer is mainly hepatitis B and hepatitis C. About one-third of patients have chronic hepatitis caused by hepatitis B virus and hepatitis C virus.

2. Cirrhosis of the liver: 50% to 90% of liver cancer patients have concurrent cirrhosis. In recent years, it has been found that the proportion of hepatitis C virus developing into cirrhosis is no less than that of hepatitis B.

3. The metabolites of aflatoxin, a chemical carcinogen, have strong carcinogenic effects and exist in moldy foods such as corn and peanuts. Foods contaminated by aflatoxin have a high incidence of liver cancer in serious areas. Alcohol, organochlorine pesticides, etc. are all suspected carcinogens.

In recent years, it has been discovered that blue-green algae growing in ponds are strong carcinogenic plants that can pollute water sources. Parasites and testicular fluke infections can stimulate bile duct epithelial hyperplasia and inhibit primary bile duct cancer.
