How does liver carcinoma (cancer) develop?

The key point for the prevention and cure of liver carcinoma (cancer) lies in the discovery and prevention of the inducing causes, early discovery and the appropriate therapy of the liver carcinoma.

Inducing causes for the development of liver carcinoma: The development of liver carcinoma is associated with the Hepatitis viruses B, C and D.

It has been proven that the Hepatitis viruses B, C and D (that are spread mainly by blood) are closely associated with liver carcinoma, while Hepatitis virus A (that spreads by food) has no correlation with liver carcinoma.

There are about 120 million carriers of the HBV surface antigen in China, which occupies 30% of the population in the world. Among them, 3 million will turn into chronic Hepatitis sufferers and about 300,000 will turn into liver cirrhosis sufferers; finally, a portion of them will develop into liver carcinoma sufferers.

The conversion process is roughly as follows:

HBV→chronic Hepatitis→liver cirrhosis→liver carcinoma

It is estimated that about 70% to 80% of liver carcinoma patients are correlated with HBV, and about 15% to 20% are correlated with HCV or HDV. The approximate remaining 5% of liver carcinoma patients are probably correlated with alcohol abuse, parasite infection or long-term use of contraceptives.
