How are blood tests used to diagnose liver cancer?

ANSWER

Blood tests that measure tumor markers -- the levels of these substances rise in the blood if someone has a particular cancer -- can aid diagnosis. Liver cancers secrete a substance called alpha fetoprotein that is normally present in fetuses but goes away at birth. An elevated fetoprotein in adults may indicate liver cancer as it is produced in 70% of liver cancers. Elevated levels of iron may also be a tumor marker.
