Primary liver cancer is a disease in which malignant (cancer) cells form in the tissues of the liver. Cancer that forms in other parts of the body and spreads to the liver is not primary liver cancer. The liver is one of the largest organs in the body. It has two lobes and fills the upper right side of the abdomen inside the rib cage. The main functions of the liver include the following:
- to make bile to help digest fat that comes from food
- to store glycogen (sugar), which the body uses for energy
- to filter harmful substances from the blood so they can be passed from the body in stools and urine
