The liver is located in the right side of the abdomen. It stores and metabolizes nutrients. It also 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. These tumors can invade nearby tissue and spread to other parts of the body.

The cause of liver cancer is not known. Research shows that certain risk factors are associated with the disease.
