16. How often should someone with chronic hepatitis B be screened for cancer?

Ever since Taiwan adopted universal vaccination, they saw a significant decrease in childhood (children less than 15) liver cancer. Most people develop liver cancer about 20 years after they have been infected. If you were infected at 20 or 25 from a blood transfusion, I would suggest that you should start getting screened in your 40's - this is not the normal recommendation. Once you develop cirrhosis, you need to be screened regularly (twice a year).
