I. Are hepatitis B and liver cancer related or not? Liver cancer is a malignant tumor on the liver, and hepatitis B is also a disease that occurs in the liver, so this situation is actually easy to make people associate with it. So is there any connection between hepatitis B and liver cancer or not? Actually, it is true that there is definitely a definite connection between hepatitis B and liver cancer! Liver cancer has many patients in China, and the mortality rate is relatively high. The liver is the metabolic center of many important substances in human body, and it also has important functions such as detoxification, secretion and excretion, once liver cancer appears, it is extremely harmful to human health. Among these liver cancer patients, most of them are developed from chronic diseases, such as hepatitis. It is clinically noted that patients with liver cancer have a history of acute hepatitis-chronic hepatitis-cirrhosis-liver cancer, which shows that hepatitis is extremely closely related to liver cancer. In domestic studies on liver cancer, it is also noted that the proportion of hepatitis in the population with high incidence of liver cancer is high, and the number of hepatitis B surface antigen (HbsAg) positive patients among liver cancer patients is significantly higher than that of HbsAg negative patients. Chronic hepatitis can also lead to liver cancer directly without going through the stage of hepatic sclerosis. This shows that there are many liver cancer patients whose disease has developed from hepatitis, so there is a strong link between hepatitis B and liver cancer. This is a reminder for people not to always neglect treatment because they think the symptoms of hepatitis B are not too serious, but in fact it may bring serious consequences if the treatment is not proper or timely. Second, since hepatitis B may lead to the formation of liver cancer, how to prevent hepatitis B? The prevention of hepatitis B is a major task in modern society, which requires the cooperation of everyone to avoid the unrestrained spread of hepatitis B virus. So, what are the measures to prevent hepatitis B in life? Hepatitis B is highly contagious and it may be transmitted through the blood by injection, in addition to transmission through the digestive tract. So do the following defensive measures: 1, injection supplies and their medical equipment should be strictly disinfected. Hold the quality of blood transfusion and blood products, and always check the health status of blood donors to see if they are carriers of hepatitis B virus surface antigen. 2, cut off the transmission of saliva, give children mouth-to-mouth feeding is a bad habit, the survey shows that in most of the hepatitis B virus carriers can catch the hepatitis B virus in their saliva. The best way to prevent mother-to-child transmission is to inject one hepatitis B immunoglobulin immediately after birth, and then inject one hepatitis B vaccine at 1 month, 2 months and 3 months of age. 4, to do a good job of family and environmental hygiene, bathing, changing clothes, washing and drying bedding. A small percentage of patients have hepatitis B transmitted by blood-sucking arthropods such as mosquitoes, bedbugs and fleas. The above introduces the relationship between hepatitis B and liver cancer and the four measures to prevent hepatitis B. I hope it will be helpful for you to do a good job in preventing hepatitis B in your life.
