Ordering the Carcinoembryonic Antigen Test
Ordering the Carcinoembryonic Antigen (CEA) test is important for monitoring certain types of cancer, especially colorectal cancer. This test helps in assessing the effectiveness of treatment and checking for cancer recurrence. Interestingly, CEA levels can also be elevated in non-cancerous conditions like inflammation or infection, making it a versatile tool in a doctor’s diagnostic arsenal.
Here are some specific benefits of the CEA test:
- Monitors cancer treatment progress.
- Detects potential cancer recurrence.
- Assists in evaluating the spread of cancer.
- Helps in diagnosing certain non-cancerous conditions.
- Provides valuable information for personalized treatment plans.
Who Should Consider the Test
Individuals undergoing treatment for colorectal cancer or those in remission may find the CEA test beneficial. For instance, a person who has completed chemotherapy might use this test to ensure the cancer has not returned.
Other scenarios where the CEA test might be considered include:
- Monitoring after surgery for cancer.
- Evaluating unexplained weight loss.
- Checking for cancer spread in the body.
- Assessing chronic inflammatory conditions.
- Investigating persistent cough or hoarseness.
Consider ordering the test if any of these situations apply to you.
How to Prepare for the Test
No fasting is required for the CEA test. If you are taking any medications or supplements, it is important to follow any specific instructions given by your healthcare provider.
