Whenever we see patients with advanced liver cancer in clinical practice, we always feel sorry for them. It is a pity that nowadays, with such a good medical condition, the disease can still develop to such a stage before it is discovered, and it is a pity why no one has given them proper health checkup advice before. According to statistics, hepatitis B virus carriers account for about 10% of the total population in China, and about 300,000 of them develop liver cancer every year, most of them are already in the middle and late stages once they are detected. Is there any way to reduce the incidence of liver cancer? Can liver cancer be detected at an early stage? The answer is yes. To significantly reduce the incidence of liver cancer, we need to significantly reduce the incidence of hepatitis B virus carriers. This work is being done by the state, and after two more generations of efforts, China can completely remove the hat of hepatitis B power. On the other hand, the risk of developing liver cancer can be reduced clinically by monitoring some programs for hepatitis B virus carriers and timely intervention, and liver cancer can be detected early through reasonable health checkups. How to reduce the risk of developing liver cancer? How to detect liver cancer at an early stage? In fact, the methods are very simple, one is not to drink alcohol, the second is regular checkups, and the third is timely treatment. If a hepatitis B virus carrier drinks alcohol for a long time, the chance of chronic hepatitis, cirrhosis and liver cancer is very high, so hepatitis B virus carriers must pay attention to this. Regular checkup means monitoring liver function, hepatitis B virus DNA, alpha-fetoprotein and other indicators once every three months, and doing ultrasound once. Through this method, chronic hepatitis, hepatitis cirrhosis, precancerous lesions or early small liver cancer can be diagnosed in time. Timely treatment and therapeutic intervention for chronic hepatitis, hepatitis cirrhosis or precancerous lesions can reduce the risk of liver cancer; timely detection and timely treatment for early small liver cancer can obtain the best efficacy.
