In liver metastases or liver disease from cancer, serum alkaline phosphatase may be progressively increased, often exceeding 20 gold A units, and γ-glutamyl transpeptidase (γ-GT) may be positive. Glutamate aminotransferase and other liver function changes are not significant. Patients tend to die within a short period of time. What are the prevention methods of liver metastasis or liver disease of cancer? 1.First of all, we should prevent viral hepatitis. Up to now, the rate of liver cancer related to viral hepatitis has been high. The effective way to prevent viral hepatitis in China is hepatitis B vaccination. It can also be said that this is a way to prevent the occurrence of liver cancer. 2. To develop good living habits. Among the good habits, the first one is to quit smoking and alcohol. The second is to develop good eating habits, which should start from dietary hygiene and living habits. We should wash our hands regularly and share meals. You cannot eat moldy and mushy food, which contains aflatoxin, a carcinogenic substance. The last thing to emphasize is quality sleep. 11:00 p.m. to 3:00 a.m. is the time for the liver to repair itself and metabolize, and this is the time to ensure that the body has gone to sleep so that the liver can get sufficient rest and rejuvenation. The burden on the liver is lightest during sleep, and the body is lying down, the liver can enjoy more blood nourishment, the most blood flowing through the liver, which is beneficial to liver repair. 3, do not drink raw water, and do not eat raw seafood, because clams, oysters and shellfish are susceptible to hepatitis A virus infection. If you want to travel to areas with high hepatitis A infection, such as mainland China, Southeast Asia, Central and South America, Africa, etc., it is best to get the hepatitis A vaccine before you leave. 4, drinking alcohol will increase the chance of fatty liver, alcoholic liver disease, people with liver disease should completely quit sprinkling. In addition, smoking is related to the development of liver cancer, so it should be possible to smoke less and quit smoking. 5, an important principle of diet is “balanced”. In order to lose weight quickly, eating only fruit for three meals and no other food, or a “low sugar diet”, a combination of high protein and low carbohydrate diet, an unbalanced diet increases the burden on the liver. The liver is responsible for converting the food it eats into a source of energy for the body. For the liver, converting non-carbohydrates into energy is more strenuous than converting carbohydrates into energy. A balanced dietary mix should be 60-70% carbohydrates (e.g. rice, pasta), 20-30% protein (e.g. meat, beans), and 10-20% polyunsaturated fats (e.g. vegetable oils).
