What _'s general knowledge of cause of disease does hepatocarcinoma have
Up till now, the cause of disease of hepatocarcinoma is not very clear, but generally think now the following factors may relate to morbidity of hepatocarcinoma.
The relation between hepatopathy and hepatocarcinoma: Have noticing clinically the patient of hepatocarcinoma often has acute hepatitis at present Chronic hepatitis Medical history of cirrhosis. Analyze from the pathological angle, in the primary liver cell cancer patient, nearly have 5 0 - 8 0 % Case with cirrhosis: And in cover cell cancer on the bile duct of the primary hepatocarcinoma, yes 1 8 .2 - 5 0 % The case, with cirrhosis. This figure explains the close relation of these two kinds of diseases, hepatocarcinoma may be resulted from excessive regeneration of hepatocyte that liver cirrhosis cause. In addition it is antigenic (H B sA g) to the surface of hepatocarcinoma and patient's hepatitis B to pass Determination,that last H B sA g, patient of hepatocarcinoma, positive rate up to 8 1 .8 2 % . This result seems to prove that has suffered from hepatitis B, but the relation between them, still remain to further study. But one point can affirm, prevent virus hepatitis, cirrhosis is very important to reducing the emergence of hepatocarcinoma.
Yellow aspergillus is and mould and plain: A large amount of scientific experimentation has already proved, use and contain the mould or his toxin's food of the yellow song, feed the experimental animal, can cause hepatocarcinoma of the animal. So someone thinks the south of Africa moister, the food incident goes mouldy less, the morbidity of hepatocarcinoma is lower too. The food that goes mouldy incident has rice, wheat, soybean, peanut, corn.
Other: Too much food which contain the inferior nitre amine compound of ingestion, parasitic disease (mainly carry the liver fluke namely Chinese branched testis fluke) .
