Clinical studies have found that about l0% of viral hepatitis develop into chronic active hepatitis, and 50% of chronic active hepatitis can develop into hepatic steatosis. Hepatitis B is predominant, followed by hepatitis C. Hepatitis A does not turn into hepatic steatosis because of its rapid recovery and good prognosis. Recent data particularly emphasize the importance of hepatitis B virus (HBV) infection in liver cancer, with at least 80% of patients with hepatocellular liver cancer having hepatitis B virus infection. It has been demonstrated that the risk of hepatocellular liver cancer in chronic hepatitis B surface antigen carriers is 40 times higher than that of the negative population. In recent years, the incidence and mortality rate of primary liver cancer in China have been on the rise. The relationship between hepatitis, hepatic sclerosis and hepatocellular carcinoma is quite close. Some people call hepatitis, hepatic steatosis and liver cancer as “three steps of liver disease”. However, this is not absolute. Experts point out that 90% of liver cancer patients have a history of hepatitis B. The persistent infection of hepatitis B virus is one of the main causes of liver cancer. If you are infected with hepatitis B virus, you must keep in mind the following 4 risk factors to avoid the attack of liver cancer: 1. Drinking alcohol Long-term alcohol consumption can promote cirrhosis or liver cancer to those who are positive for hepatitis B surface antigen; 2. Eating rotten oil Stale animal and vegetable oils are toxic and may cause cancer; 3. Eating moldy food When mold contamination is found in food, oil and milk, it is prohibited to eat; 4. Treating liver disease as it is.
