The possibility of liver cancer in ordinary people is very small and there is no need to worry too much. However, if you have hepatitis B, hepatitis C, cirrhosis and other liver diseases, you should be especially careful. As a large country with hepatitis B, 7.18% of the total population are hepatitis B virus carriers in China. Clinical studies have found that 85% to 90% of liver cancers are related to hepatitis. Among them, hepatitis B, hepatitis C and hepatitis A are different in that they are more likely to turn into chronic hepatitis, and the repeated prolonged attacks of hepatitis may lead to cirrhosis, which will turn into liver cancer with the migration of time. Generally speaking, unless the tumor that appears in the liver is already large, there are few symptoms. Many of the legendary symptoms are similar to those of digestive diseases and cannot be simply judged, but still need to be examined carefully before a conclusion can be made. Hepatitis B vaccination is the best way to prevent hepatitis B. China started vaccinating against hepatitis B in the 1980s, and the incidence rate is generally declining, but it will take decades to see significant results. Therefore, people at high risk should pay special attention. If one is still unfortunate enough to be infected with hepatitis B, it often takes ten or even twenty years from the time of infection to the onset of disease, while hepatitis C is a little shorter. There are clinical examples of young patients who got hepatitis B from mother-to-child transmission and developed liver cancer in just a few years at the age of teenagers. However, paying attention to the standard treatment of hepatitis B and avoiding bad lifestyle habits can reduce the possibility of developing liver cancer. The most common ones we all know are like alcoholism, drinking one or two pounds of liquor every day. That kind of bad eating habits and lifestyle may itself cause hepatitis and cirrhosis, and if you already have hepatitis B or C, the disease is likely to be aggravated. The main way of transmission of hepatitis B and C is blood, like eating together, shaking hands and so on will not spread. But including mother-to-child transmission, blood transfusions, drug use, including to some small informal dental clinics, incomplete sterilization may be transmitted. In addition, there are some local customs and habits to eat moldy food, the possibility of liver cancer induced by aflatoxin contamination will be very high. However, patients with hepatitis B, hepatitis C and cirrhosis caused by some viruses are at high risk of liver cancer and generally need to have a medical checkup once every six months. If liver cancer is found to be highly suspicious but cannot be diagnosed for the time being, imaging and laboratory tests should be done once every three months or so. Scientific diet and timely medical examination will minimize the risk of liver cancer. In this way, you can choose to go far away to see that bigger world.
