Overview
Other Diagnostic Studies
Serum tumor marker test
Serum tumor marker test: A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs, tissues, or tumor cells in the body. Certain substances are linked to specific types of cancer when found in increased levels in the blood. These are called tumor markers. The blood of children who have liver cancer may have increased amounts of a protein called alpha-fetoprotein (AFP) or a hormone called beta-human chorionic gonadotropin (β-hCG). Other cancers and certain noncancerous conditions, including cirrhosis and hepatitis, may also increase AFP levels.
Biopsy
The removal of cells or tissues so they can be viewed under a microscope to check for signs of cancer. The sample may be taken during surgery to remove or view the tumor. A pathologist views the sample under a microscope to determine the type of liver cancer.
