CEA (carcino embryonic antigen), is a type of protein molecule that can be found in many different cells of the body, but is typically associated with certain tumours.
Both benign (harmless) and malignant (cancerous) conditions can cause elevated levels of CEA.
Raised CEA is commonly seen in cancer of the colon and rectum but also in cancers of the pancreas, stomach, breast, lung, and certain types of thyroid and ovarian cancer. Non-cancerous conditions which can lead to elevated CEA include infections, inflammatory bowel disease, pancreatitis, cirrhosis of the liver and some benign tumours in the same organs where CEA may also indicate cancer.
This test is not recommended as a screening test but rather as a test to monitor an already diagnosed cancer or a recurrence of cancer following treatment. Its use as a screening test is not established. False positives and false negatives may cause undue anxiety or unwarranted reassurance. If you wish to take this test as a screening test please be aware of its limitations.

Please see your doctor if you are suffering any unusual symptoms which persist - do not use these tests to self-diagnose. Tumour markers are most useful when viewed in conjunction with a clinical examination. Results do not constitute a diagnosis of cancer and markers are often tested to monitor treatment when cancer has already been diagnosed, or to check that it has not returned. Cancer markers can be elevated in benign conditions and results often produce false positives. Sometimes tumour markers can be normal even though cancer is present.
Our tests are not a substitute for seeing your doctor, especially if you are suffering symptoms. Our doctors will interpret your results based on the information you have provided, but will not diagnose, consult or provide any treatment. You will be advised to see your doctor for any necessary follow-up action.
Carcino embryonic antigen (CEA) is a glycoprotein that is normally found in small amounts in the cells. In cases of cancer, predominantly bowel cancer but also breast, lung, pancreatic and stomach cancers, levels of CEA can be elevated. It is generally used to monitor an already diagnosed cancer or to check that cancer has not returned.
An elevated result is not necessarily diagnostic of cancer (CEA can also be raised in other non-malignant conditions) and it does not indicate where a cancer is located. However, an elevated result should be investigated, especially if symptoms are present.
Its use as a screening test is not established. Like other tests for tumour markers, a change in level over time may be more significant than the absolute level at a given point in time.
