CEA – Carcino Embryonic Antigen Tumor Marker

The CEA test measures the level of carcinoembryonic antigen (CEA) in the blood. CEA is a protein normally found in the tissue of a developing baby in the womb. The blood level of this protein disappears or becomes very low after birth. In adults, an abnormal level of CEA may be a sign of cancer.

Smoking may increase CEA level.

The normal range is 0 to 2.5 micrograms per liter (mcg/L). In smokers, the normal range is 0 to 5 mcg/L.

A high CEA level in a person recently treated for certain cancers may mean the cancer has returned.A higher than normal level may be due to the following cancers:

  • Colon,Rectum,Pancreas or Stomach cancer
  • Breast cancer
  • Lung cancer
  • Ovary cancer
  • Some other cancers

Higher than normal CEA level alone cannot diagnose a new cancer. Further testing is needed.

An increased CEA level may also be due to:

  • Liver and gallbladder problems
  • Heavy smoking
  • Inflammatory bowel diseases (such as ulcerative colitis or diverticulitis)
  • Lung infection
  • Inflammation of the pancreas (pancreatitis)
  • Stomach ulcer
