Hepatocellular Carcinoma Development

As with all cancers, hepatocellular carcinoma arises as the result of genetic mutation, which leads to an abnormally high rate of cellular replication and/or causes cells to avoid programmed cell death (apoptosis). In these cells, the damaged DNA is not repaired and neither do the cells die. Instead, they multiply and give rise to increasing amounts of abnormal cells that contain the same defective DNA.
