cancer marker test - male

These tests look for tumor markers, sometimes called cancer markers, in the blood, urine, or body tissues. Tumor markers are substances made by cancer cells or by normal cells in response to cancer in the body. Some tumor markers are specific to one type of cancer.

• Serum CEA (intestine)
• Serum Ca 19.9 (Pancreatic)
• Serum AFP (Liver)
• Serum HCG total (Testicles)
• Serum Free PSA (Prostate Specimen Antigen)

These tests are most often done on people already diagnosed with cancer. Tumor markers can help find out if your cancer has spread, whether your treatment is working, or if your cancer has come back after you've finished treatment.

It might also be useful in screening tests that aim to detect cancer early, before there are any symptoms.
