 Hi, I'm Dr. Olyth Selvan, Consulant Heptoologist and Chairman Division of Liver Transplantation, Manipal Hospital's Bangalore. Hepatitis B causes liver damage. And if you have liver damage, you are prone to get liver failure, which usually happens after a few decades. And patients with hepatitis B are also prone for getting liver cancer without liver damage. And that is the leading cause of liver cancer in our country.
