Liver cancer has a high incidence rate, and about 80% of patients are diagnosed at an advanced stage. According to statistics, in my country, 110,000 people die from liver cancer every year, including 80,000 men and 30,000 women, accounting for 45% of the world's liver cancer deaths.
Liver cancer is so scary, who are the high-risk groups?
Who are the high-risk groups?
(1) Hepatitis B patients:
Epidemiology Statistics show that areas where hepatitis B is prevalent are often areas with a high incidence of liver cancer. People who have had hepatitis B are indeed more likely to develop liver cancer than people who have not had hepatitis B. This risk As much as 10.7 times more.
Hepatitis B virus may be the main initiating factor among many factors in the pathogenesis of human liver cancer.
(2) People with unclean diet: long-term consumption of moldy food, food containing nitrite and lack of trace element selenium in food are also important factors in promoting liver cancer.
(3) Smokers and alcoholics: People with alcoholism have a high incidence of liver cirrhosis and , and the relationship between cirrhosis and liver cancer is very close. If you increase the amount of smoking, it will accelerate and aggravate the formation of cirrhosis and promote the occurrence of liver cancer.
(4) Chronic cholestasis/chronic cardiac insufficiency, hepatic vein obstruction: long-term cholestasis can lead to liver cell inflammation and bile duct reaction, and even necrosis, forming biliary cirrhosis. Chronic cardiac insufficiency and hepatic vein obstruction can cause liver congestion, leading to hepatic cell necrosis and degeneration due to hypoxia, eventually leading to liver cirrhosis.
(5) Those who take medicine for a long time and are exposed to chemical poisons.
(6) Metabolic disorders: genetic metabolic defects such as hemophilia can also cause this disease.
How to detect liver cancer early
Early detection of liver cancer is of great significance to treatment and prognosis.
However, how to detect liver cancer early? This requires us to conduct a general survey of the appropriate population and adopt further diagnostic methods.
Census refers to a means of finding patients among healthy people by asking medical history, physical examination or some kind of test method.
Which groups are the targets of the census? What are the methods of census?
The targets of the census are mainly high-risk groups for liver cancer, such as: HBsAg positive, or with a history of chronic hepatitis, over 35 years old, with a family history of liver cancer, excessive drinking and smoking, Although the incidence of hepatitis C is not high in our country, should also be considered a high-risk factor. Patients with clinical symptoms should also be examined in time. The inspection method of
is AFP detection and combined with ultrasound imaging. Because using AFP alone will miss 50% of small liver cancers that are less than 3 cm, while ultrasound is more than 85% sensitive to liver cancer and can detect tumors of 1 to 2 cm. The interval between inspections should be less than 8 months. 6 months is best.
How to prevent liver cancer
① Water change: mainly refers to changing stagnant water into living water, from drinking pond water and house ditch water to drinking well water, deep well water, and tap water. Cities are switching to less polluted water sources as tap water and promoting the use of water purifiers.
② Anti-mildew: Aflatoxin mainly comes from corn, peanuts and their products. Therefore, it is necessary to promote eating rice instead of corn in the diet and reduce the consumption of excessive peanuts and their products. In recent years, it has been found that green tea can reduce the effect of aflatoxin in inducing liver cancer in animals, so drinking green tea is advocated.
③ Prevent hepatitis: This is the most important link in preventing liver cancer. We have already known that hepatitis B, hepatitis C and liver cancer are closely related, and they are all blood-borne infections and can be transmitted vertically from mother to child. Therefore, avoiding blood-borne hepatitis and timely vaccination of hepatitis vaccine will reduce the occurrence of liver cancer.
Of course, the above guidelines only talk about some of the most important factors. At the same time, maintaining an optimistic mood, not smoking, not being addicted to alcohol, and developing a good lifestyle will all play a positive role in preventing liver cancer.
