Generally speaking, the prognosis of hepatitis is good for most of them, and they can recover smoothly from acute hepatitis, but many patients with hepatitis B do not recover for a long time, and some of them develop cirrhosis, and very few of them develop liver cancer. According to research, 75% to 80% of cirrhosis is developed from chronic hepatitis B. It has been reported abroad that the risk of liver cancer in chronic hepatitis B surface antigen carriers is more than 200 times higher than that in non-carriers. Some scholars believe that since hepatitis B virus is the culprit, prevention and treatment of hepatitis B can reduce the occurrence of liver cancer, while scientists with different opinions believe that the factors of liver cancer are very complicated, and hepatitis B virus is only the initiating cause. Because many people are infected with hepatitis B virus, but after all, only a small number of people develop cirrhosis and primary liver cancer. Prevention and treatment of hepatitis B is very important, but a single measure may not solve the problem, we should prevent the chronicity of hepatitis through comprehensive measures to prevent the occurrence of cancer. 1.When you have hepatitis B, you should go to a specialized hospital to receive systematic and standardized treatment as early as possible; 2.Regular liver function, virological index, liver fibrosis index, alpha-fetoprotein, ultrasound and other tests; 3.Avoid the use of drugs that damage the liver; 4.Avoid the stimulation of harmful physical factors and reduce the exposure of X-rays and radioactive substances to the liver; 5.Minimize and treat various infections as early as possible and avoid various traumas and surgeries 6.Avoid contact with and consumption of toxic and harmful foods and minerals; 7.Cultivate good habits of life and living, appropriate physical and mental exercise, and maintain optimism; 8.Pay attention to nutrition, the diet should be light, and should be rich in vitamins and proteins, etc.
