Hepatitis B can progress to cirrhosis (liver scarring), liver cancer and liver failure, so knowing what is happening in your liver is important for staying healthy and well. Understanding the phases of Hepatitis B and knowing what phase you are in will determine whether you need to consider treatment (antiviral therapy).
