Clinical Information

  • Your liver is the largest organ inside your body. It filters harmful substances from the blood, digests fats from food and stores the sugar that your body uses for energy. Primary liver cancer starts in the liver. Metastatic liver cancer starts somewhere else and spreads to your liver. Risk factors for primary liver cancer include
    • having hepatitis
    • having cirrhosis, or scarring of liver
    • being male
    • low weight at birth
    symptoms can include a lump or pain on the right side of your abdomen and yellowing of the skin. However, you may not have symptoms and the cancer may not be found until it is advanced. This makes it harder to treat. Treatment options include surgery, radiation, chemotherapy or liver transplantation. nih: national cancer institute
