Understanding Your Carcinoembryonic Antigen (CEA) Test
What It Is: The Carcinoembryonic Antigen (CEA) test is a blood test that measures the level of CEA, a protein normally found in the tissue of a developing baby in the womb. In adults, an abnormal level of CEA can be a sign of certain types of cancer.
Why It's Done:
Diagnosing Cancer: This test helps in the diagnosis of certain cancers, such as colorectal, lung, breast, and pancreatic cancers.
Monitoring Treatment: It’s used to monitor the effectiveness of cancer treatment, checking if the tumor is growing, spreading, or diminishing.
Detecting Recurrence: The test can help detect the return of cancer after treatment.
How the Test Works:
Preparation: No special preparation is usually needed, but it’s always best to follow your healthcare provider’s instructions.
Sample Collection: A healthcare professional will draw a small sample of your blood, usually from a vein in your arm.
Laboratory Analysis: The blood sample is sent to a lab where the level of CEA is measured.
Understanding the Results:
Normal CEA Levels: Generally indicate that there is no significant presence of cancer.
Elevated CEA Levels: Could suggest the presence of cancer or a return of cancer after treatment. However, elevated levels can also be due to other conditions, such as inflammation, infection, or smoking.
Why Your Doctor Might Order This Test:
Cancer Diagnosis: To help diagnose certain types of cancer.
Monitoring Treatment Progress: To see how well cancer treatment is working and whether the cancer is shrinking or spreading.
Detecting Recurrence: To check if cancer has returned after treatment.
Evaluating Symptoms: If you have symptoms like unexplained weight loss, fatigue, or changes in bowel habits, this test can help determine if cancer is the cause.
Symptoms of Cancer:
Unexplained weight loss
Fatigue
Persistent pain
Changes in bowel or bladder habits
Unusual bleeding or discharge
If you experience any of these symptoms, it's important to discuss them with your healthcare provider.
Lifestyle and Management: Depending on your results, your healthcare provider might recommend further tests, treatments, or lifestyle changes to manage your health. Regular monitoring and check-ups are key to managing cancer effectively.
