Table of Neoplasms
This code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.
Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Patient Education
Liver Cancer
Your liver is the largest organ inside your body. It helps your body digest food, store energy, and remove poisons. 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 B or C
- Heavy alcohol use
- Having cirrhosis, or scarring of the liver
- Having hemochromatosis, an iron storage disease
- Obesity and diabetes
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 until the cancer is advanced. This makes it harder to treat. Doctors use tests that examine the liver and the blood to diagnose liver cancer. Treatment options include surgery, radiation, chemotherapy, or liver transplantation.
