According to the data released by China CDC, it is estimated that there are about 90 million chronic hepatitis B virus carriers in China, accounting for 1/3 of the total number of hepatitis B virus carriers in the world. In other words, there is one HBV carrier in every 14 people. Studies have found that about 60%-80% of patients with liver cirrhosis and liver cancer in the world are caused by hepatitis B. Therefore, we have to pay attention to the relationship between hepatitis B and liver cancer.
Simple hepatitis B virus will not bring particularly serious impact on the liver, but after hepatitis B virus enters the liver cells, at a certain moment, the human body's own immune system will be activated, attacking those liver cells that are infected by the virus but still intact, leading to the occurrence of acute hepatitis B. When the liver cells are attacked by the immune system or eaten by the virus, they will lose their normal functions and easily form cirrhosis. If this stimulation continues, liver cancer may follow.
The process of hepatitis B developing into liver cancer can be simply summarized into three steps, namely: chronic hepatitis-cirrhosis-liver cancer.
But what needs to be understood is that not 100% of hepatitis B will develop into liver cancer, so you don't have to panic too much.
How long it takes for liver disease to turn into liver cancer depends on the specific situation of the patient, and there is no absolute time. Under normal circumstances, it will not be said that a person who has just got hepatitis B will immediately become liver cancer in the second year, from hepatitis B to chronic active hepatitis, cirrhosis to liver cancer. It usually takes a long time. Five, ten or even twenty years is possible, but it is not an absolute law. Some people will have a short transition time.
Therefore, in view of its uncertainty, we need to pay attention to observation and regular screening, so as to solve the problem in time, especially for the high-risk groups of liver cancer, and we should be more vigilant.
Wu Jianxiong, director of the Department of Hepatobiliary Surgery, Cancer Hospital of China Academy of Medical Sciences, said that the following five categories of people belong to the high-risk group of liver cancer:
Patients with hepatitis B and hepatitis C for more than five years and corresponding virus carriers;
Patients with chronic hepatitis, people who have long been addicted to alcohol, eating moldy food and drinking water with excessive heavy metal content;
People who have symptoms such as discomfort and pain in the liver area and have detected abnormal alpha-fetoprotein, but have not been diagnosed with liver cancer;
Men over 40 years old or women over 50 years old;
People with a family history of liver cancer.
Therefore, these people must do a good job in the prevention of liver cancer.
Liver cancer is not difficult to prevent, mainly for these high-risk factors.
First, strengthening the vaccination of healthy people, and standardizing the treatment and disease management of patients with antiviral treatment indications are of vital importance to the prevention of liver cancer.
Second, prevent liver cancer and advocate a healthy lifestyle. Stay away from alcohol, excessive intake of alcohol can increase the burden on the liver and easily lead to fatty liver. After a long time, it can induce liver fibrosis and cirrhosis, and finally develop into liver cancer; Ensuring adequate sleep and staying up late for a long time will affect the self-repair mechanism of the liver, endanger the health of the liver and make it pathological, thus increasing the risk of liver cancer; Stay away from moldy food and aflatoxin, which has a strong carcinogenic risk and is one of the main factors leading to liver cancer.
Third, regular physical examination is of great significance to prevent liver cancer, especially for high-risk groups of liver cancer. Serum alpha-fetoprotein and liver ultrasound examination are the main methods for early screening of liver cancer, and it is suggested that the above-mentioned high-risk groups should be examined every six months 1 time. It should be emphasized here that the physical examination is every six months 1 time, not every year, because it takes about 1 0 months for liver cancer to develop from canceration to advanced stage, and 1 year 1 time may miss the opportunity to find early liver cancer.
Conclusion: The prognosis of liver cancer is poor, and early detection of liver cancer is of great significance. People at high risk of liver cancer must pay attention to it and take preventive measures quickly. # Breeze Plan ##39 Health Super Group # # Bring Health Home #
