Where is hepatocarcinoma from _'s general knowledge
The focal point that hepatocarcinoma prevents and cures lies in finding and preventing the cause of disease bringing out hepatocarcinoma, finding in early days and treating rationally. Then, how on earth did hepatocarcinoma take shape?
Inducement: Relate to B, third, man type hepatitis virus
Scientific research personnel have already verified, mainly B-mode, C-mode and in close relation with man type hepatitis virus and hepatocarcinoma through what the blood is infected, and the first type hepatitis virus that transmits through the diet has nothing to do with hepatocarcinoma.
There are persons who carries antigen of surface of 120 millionth hepatitis B in our country, account for 30% of population in whole world, among them 3 million people will transfer to chronic hepatitis, about 300,000 people transfer to liver cirrhosis, some hepatitis B patients change into hepatocarcinoma finally.
Hepatocarcinoma transforms the course roughly as follows: Hepatitis B Chronic hepatitis Liver cirrhosis Hepatocarcinoma. The statistics show, hepatocarcinoma the intersection of hepatitis B and person who correlated with account for 70- 80% in the patient, person who correlated with about 15- 20% with man hepatitis, another 5% the intersection of hepatocarcinoma and patient might infect, take contraceptives, have something to do for a long time by parasite, with getting drunk.
Defend hepatitis first
So, preventing hepatocarcinoma must prevent virus hepatitis at first. There are four kinds of infection routes of hepatitis B: Mother-to-baby transmission generally thinks that nearly there are 1/3 (about 30 million) in the person who carries antigen of surface of hepatitis B Come from mother-to-baby transmission. Because it is early to infect, more than 90% develop into chronically and infect. Studies have suggested, the chronic danger that melt is about 30% after the children before 6 years old are infected with, and only 5% are chronic to melt in the infeted of the acquired character in adulthood.
It is an important route that the blood propagates and cures the source and spreads and transmits through blood. For instance: Transfuse blood or use the blood products, the blood is dialysed, stab, share saver and toothbrush, tattoo, fill a tooth etc. by the syringe needle or scalpel accident.
The seminal fluid of the person who carries antigen of surface of male hepatitis B of transmission through sex is infective. ***Must use the condom hour.
Other way virus may also be bitten and spread through damaged oral cavity mucous membrane and insect. In still little our country, transmit through blood, mainly infect through blood transfusion.
Inject vaccine of hepatitis B
There are 1/10 of the hepatitis B patients in our country, it is impossible not to contact the hepatitis virus at all in life. Fortunately already there is safe and effective hepatitis B vaccine that has come out now, the success rate that injects, brings out the protective antibody is more than 97%. Our country has already popularized to infant and pre-school children and children vaccine injection plan now, it is estimated the incidence of hepatocarcinoma will drop greatly 20 years later.
