简介：In fact， concerning the liver cancer in the Asia Pacific， largely there is no major change in incidence of HCC that is likely related to the high prevalence of hepatitis B in our region. Most of the countries in the Asia Pacific region where HCC or liver cancer is still of high prevalence is because they have a very high prevalence rate of hepatitis B. Although we have a vaccination to decrease the infection rate， but the effects will not be seen until 20 or 30 years later.
