Liver cancer is a disease in which excessive cell growth occurs in the liver, resulting in tumours (solidified masses of cells and tissues) that may spread to other areas of the body. In the liver, there are two kinds of tumours: benign (harmless) and malignant (harmful) (causes cancer). Hepatocellular Carcinoma is responsible for around 80% of liver cancer deaths, according to data published by the American Liver Foundation. In the case of liver cancer, the normal functioning of the liver is impaired, which ultimately leads to death.
