Malignant Tumors
While there are other types of liver cancer, the most common form in adults is called hepatocellular carcinoma (he-pat-o-CELL-u-lar car-sin-O-muh).It begins in the hepatocytes, the main type of liver cell. About 3 out of 4 primary liver cancers are of this type. Most of the information in the other sections of this article refers only to hepatocellular cancer.
This type of cancer can have different growth patterns. Some begin as a single tumor that grows by expanding. Only late in the disease does it spread to other parts of the liver.
A second type of liver cancer spreads tentacle-like growths through the liver almost from the beginning and is not confined to a single tumor. This is most often seen in people with liver cirrhosis and is the most common pattern seen in the United States.
In a third type, the cancer develops as nodules in several parts of the liver.
(Sometimes the pattern isn't clear and the cancer doesn't fit any of these.)
Doctors can identify several subtypes of hepatocellular cancer by looking at tissue under a microscope. The most important is called fibrolamellar. This subtype has a better outlook (prognosis) than other forms of liver cancer.
