Epidemiological statistics show that hepatitis B is endemic areas are often in areas of high liver cancer, hepatitis B patients who had suffered from hepatitis B than in those who did not suffer more chance of liver cancer, the risk is as high as 10.7 times the more.
In the elderly: most of the high incidence of liver cancer after the age of the age of 40, which is due to the role of carcinogenic factors need to have a cumulative process, this process for decades or even years.
Therefore, patients with liver cancer in the elderly between the ages of majority, 50-60 is a high incidence of age. In addition, the occurrence of liver cancer and related immune function decline. Into middle age, the thymus gradually shrink, and therefore closely related to the thymus endocrine cell immune function also gradually weakened, the body can not effectively exclude the abnormal cells, cancer also took the opportunity to germinate.
Male: male patients suffering from liver cancer significantly more than female.
Under normal circumstances, liver, male to female ratio of 7-10:1, that is, the number of male patients with liver cancer is women’s 7-10 times. Why is the male liver cancer high-risk populations, currently there is no definite explanation. However, there are many medical experts believe that women in vivo analysis of the female hormones for some liver cancer risk factors have a certain antagonism.
Hepatitis B patients: Epidemiology and Statistics indicate that hepatitis B is endemic areas are often in areas of high liver cancer, hepatitis B patients who had suffered from hepatitis B than in those who did not suffer more chance of liver cancer, the risk of Up to 10.7 times. Some scholars believe that the way hepatitis B virus cause liver cancer is the result of prior hepatitis B virus causing hepatitis B, hepatitis leads to cirrhosis, the liver cells dysplasia, and then develop into liver cancer; Other scholars believe that chronic hepatitis without cirrhosis stage could be a direct result of the occurrence of liver cancer. But they have different points of view that is consistent, namely: hepatitis B virus may be the factors of human liver cancer starts in the main factor.
Food contaminated by: Long-term eating moldy food, drinking foods containing nitrite, as well as the lack of selenium in food is also an important factor in precipitating liver.
Mildew of aflatoxin in food is a major factor in inducing cancer, aflatoxin is by far the only clear that they have carcinogenic effects of substances. It is also one of the causes of liver cancer secondary. Nitrite exists in nature and a lot of foods, vegetables in the average concentration of nitrite is about 4 mg / kg, beans higher, up to 10 mg / kg. Nitrite salt is not accumulate in the body, it can be discharged through the urine, the daily diet of nitrite does not cause harm to humans. A large number of nitrite to be able to greatly harm the human body, it can be transformed into nitrosamines substances, such substances have a clear carcinogenic effect.
Addicted to alcohol and tobacco are: those who have alcohol addiction, a high incidence of cirrhosis of the liver, while the relationship between cirrhosis and liver cancer and very deep. If we add a large number of smoking, will accelerate, increasing the formation of cirrhosis of the liver and promote the occurrence of liver cancer.
Strictly speaking, alcohol is not a direct cause of illness, but alcohol is a carcinogen’s assistant or salesman, can promote the carcinogenic effects of carcinogens, but also suppress the immune system function. In addition, alcohol can stimulate the secretion of pituitary gland to speed up the rate of cell division and increase susceptibility to cancer.
To remind you: regular inspection is essential for patients with liver cirrhosis
From hepatitis B patients, to cirrhosis, liver ascites and liver cancer, liver disease progress on this “no return” on the full of fear and helplessness. Cirrhosis of the liver is the intractable disease, if the development to the liver, “Liver blood flow strong, nutrient-rich”, the transfer of early, high mortality, even through surgery or radiotherapy and chemotherapy, Chinese medicine, immunization and other treatment, 3 years survival rate remains less than 30%. So, when the scene talked about cirrhosis of the liver at the summit of this issue, from Beijing, Shanghai, Guangzhou and Shandong consensus of experts in the four liver disease called cirrhosis of the liver in patients with liver disease, especially liver disease have to go to a professional hospital on a regular basis liver gong for various tests, and early treatment to prevent cancer.
