Hepatocellular cancer usually has a poor prognosis due in part to which of the following factors?
A) Surgical options do not exist because removal of all or part of the liver is a threat to health.
B) Liver cancer typically metastasizes at a much earlier stage than other cancers.
C) Liver tumors are poorly differentiated due to the low density of hepatic tissue.
D) The nonspecific symptomatology of liver cancer leads to a diagnosis at a late stage.
Ans: D
Feedback:
Primary cancers of the liver are often far advanced at the time of diagnosis. This is partly due to the fact that the manifestations are often insidious in onset and masked by those related to cirrhosis or chronic hepatitis. Surgical options exist, and metastasis does not occur earlier than in other types of cancer, although the liver is a common site of secondary cancer. Liver tumors do not lack differentiation.
