This document summarizes information from Samuel So on liver cancer and hepatitis B. It finds that liver cancer is the 7th most common cancer worldwide and the 2nd leading cause of cancer deaths. The Western Pacific Region has the greatest burden of liver cancer, with 66% of new cases and deaths each year. Chronic hepatitis B is highly prevalent in many Asian countries and is a major risk factor for liver cancer. Hepatitis B vaccination has significantly reduced chronic infection rates and could eliminate transmission. However, challenges remain in screening, treatment and public awareness. Expanding access to antiviral therapy and improving prevention through vaccination are key to reducing the future burden of liver cancer.
