Cirrhosis is caused by repeated liver damage resulting in liver atrophy and structural damage. Generally speaking, some of the injured liver cells will die after damaged, but the liver cell can be regenerated, so that the injured part can be healed. However, if there is chronic and continuous liver damage, some of the damaged areas will have scars. Because the scar tissues do not have any function, too many scars will affect the normal function of the liver, resulting in cirrhosis eventually. Cirrhosis can cause a series of complications and may develop into cancer. Chronic hepatitis B, chronic hepatitis C and alcoholic liver disease are the common causes of cirrhosis.
