Chronic hepatitis B surface antigen carriers with liver function abnormalities are considered to have chronic hepatitis B. Hepatitis B is a high risk factor for liver cancer, but not all patients with hepatitis B end up with liver cancer, only the high-risk group. There are a few hepatitis B patients who do not get well for a long time and gradually develop into cirrhosis, and a few of them develop into liver cancer. According to research findings, 75%~80% of cirrhosis is developed from chronic hepatitis B. Therefore, chronic hepatitis B – cirrhosis – liver cancer is called “three steps of liver disease”. The risk of hepatocellular carcinoma in chronic hepatitis B surface antigen carriers is more than 200 times higher than that in non-carriers, and more than 95% of primary hepatocellular carcinoma patients are evolved from chronic hepatitis B surface antigen carriers through the “trilogy”. Therefore, preventing hepatitis B is conducive to reducing the occurrence of liver cancer. Do not eat moldy food, the diet should be light, do not eat too much meat and sugar. Meat in excess of protein and sugar food into fat, stored in all parts of the body, of which the liver is also the focus of storage, long-term body obesity, is bound to form a fatty liver, so that the sick liver is overburdened, contributing to the deterioration of hepatitis B. It is better for patients to arrange a diversified and balanced diet, especially to control body weight, with various staple foods (rice, flour, etc.), lean meat, fresh aquatic products, eggs, soybean products, various vegetables, fruits, vegetable oils, and appropriate sugars as the main focus, and less animal fats, deep-fried products, salted meat, full-fat milk, and so on. Factors that develop into primary liver cancer, besides viral causes, aflatoxin in food, excessive nitrosamine in drinking water, close contact with certain metals, such as platinum, copper, zinc, etc., are all related to the occurrence of liver cancer. Strictly prohibit alcohol abuse The main component of alcohol is ethanol, which can be transformed into acetaldehyde in the liver, directly damaging the liver and causing degeneration and necrosis of liver cells. Hepatitis B patients drinking alcohol, can be said to add insult to injury, can make the condition accelerate to cirrhosis, or even liver cancer direction. Patients in the party occasion, available drinks, mineral water instead of alcohol, white wine, beer should be prohibited. In addition, the occurrence of liver cancer is also related to the immunity of the body. Under normal circumstances, cells in the human body often undergo cancerous changes and may form cancerous cells, but the immune system of the human body has the ability to remove these cells and does not undergo cancerous changes. When the body’s immunity is weakened, it is easy for cancer to occur. Strengthening the body’s immunity is also an important aspect of preventing liver cancer from occurring. If you have hepatitis B, you should prevent the chronicity of hepatitis through comprehensive measures to prevent the occurrence of cancer. Avoid the use of liver-damaging drugs as much as possible; avoid the stimulation of harmful physical factors and reduce the irradiation of liver by X-ray and radioactive substances; reduce and treat all kinds of infections as early as possible and avoid all kinds of traumas and surgeries. Anesthesia and surgical trauma are all unfavorable to the recovery of liver function. If necessary, you should try to choose to do the surgery after the recovery of liver function. Strictly prohibit the indiscriminate use of drugs The liver is the body’s largest metabolic organ, all drugs have to be decomposed, transformed, detoxification, metabolism, indiscriminate use of “hepatoprotective drugs” is bound to aggravate the metabolic burden of the liver. In addition, the complexity of various drug components, chemical and antagonistic effects between drugs may lead to increased liver damage. Therefore, patients must be standardized under the guidance of specialists to use drugs, the principle is: less but fine, safe and effective shall prevail.
