The liver is located in the right side of the abdomen. It stores and metabolizes nutrients, and filters and stores blood. Liver cancer is the growth of cancer cells in the liver.
Cancer occurs when cells in the body divide without control or order. If cells keep dividing uncontrollably, a mass of tissue forms. This is called a growth or tumor. The term cancer refers to malignant tumors. They can invade nearby tissue and spread to other parts of the body.
