Liver cancer can develop even without hepatitis, because among the factors of liver cancer, viral hepatitis is only a common factor in the development of liver cancer, and there are other factors besides viral hepatitis that lead to the occurrence of liver cancer. The common ones are as follows: 1. Liver cirrhosis. Many patients with liver cancer develop on the basis of cirrhosis, which can be caused by liver parasitic disease or alcoholic cirrhosis, etc. 2. Aflatoxin. Frequent consumption of corn, peanuts and other foods that are easily moldy has a high content of aflatoxin, so liver cancer is prone to occur. 3. Genetic factors. Studies have found that some genetic factors also play a certain proportion in the occurrence of liver cancer.4. Pollution of living drinking water. For example, often drinking stagnant water, such as pond water, etc.
