Rising CEA Levels: Should You Worry About Cancer?

Health Check Report CEA Level

Hello Dr.
Hou, I have been undergoing self-paid health check-ups for the past four years, and the results of various tests have generally been normal.
However, the tumor marker test for CEA has gradually increased over the years, with values of 1.38 two years ago, 1.58 the year before last, 1.74 last year, and 2.25 this year.
I would like to ask Dr.
Hou whether the gradual increase in my CEA levels, although still below the normal threshold of 5, indicates a potential risk of cancer.
Should I undergo any further examinations? P.S.
My AFP, PSA, and CA-19-9 levels have all decreased over the years, my fecal occult blood test was negative, my chest X-ray was normal, and all other test results are within normal ranges.
Thank you for your response, Dr.
Hou!

LEA is a tumor marker generally used to assess the likelihood of cancer; however, its limitation is that a normal result cannot completely rule out the presence of cancer.
In cases where multiple tests return normal values, the probability of cancer is typically low, and continued monitoring is usually sufficient.
However, it is also advisable to discuss this with a gastroenterologist.

More Info

When it comes to rising levels of Carcinoembryonic Antigen (CEA), it is understandable to feel concerned, especially given the context of your health history and family background. CEA is a tumor marker that can be elevated in various types of cancers, particularly colorectal cancer, but it is not exclusively indicative of cancer. It is important to interpret these results in conjunction with other clinical findings and tests.

Understanding CEA Levels
1. Normal Ranges and Variability: CEA levels can vary based on several factors, including the laboratory methods used for testing. Different labs may have slightly different reference ranges, which can lead to confusion when comparing results over time. Generally, a CEA level below 5 ng/ml is considered normal, but levels can be influenced by non-cancerous conditions such as smoking, inflammatory diseases, and even benign tumors.

2. Rising CEA Levels: Your CEA levels have shown a gradual increase from 1.38 to 2.25 ng/ml over the past four years. While these levels remain below the typical threshold for concern (5 ng/ml), the upward trend could warrant further investigation. It is essential to note that a rising CEA level does not automatically indicate cancer. Many factors can contribute to elevated CEA levels, including benign conditions and lifestyle factors.

3. Family History: Given your family history of colorectal cancer, it is prudent to be vigilant. Family history is a significant risk factor for developing certain cancers, including colorectal cancer. Regular screenings, such as colonoscopies, are recommended, especially if you have a first-degree relative who has had colorectal cancer.

Recommended Actions
1. Consultation with a Specialist: It would be beneficial to consult with an oncologist or a gastroenterologist who can provide a more comprehensive evaluation of your situation. They may recommend further testing, including imaging studies or a colonoscopy, to rule out any underlying issues.

2. Additional Tests: Since your other tumor markers (AFP, PSA, CA-199) are decreasing and your fecal occult blood test is negative, this is reassuring. However, continuing to monitor your CEA levels and possibly repeating the test in a few months could provide more insight into whether the trend continues or stabilizes.

3. Lifestyle Considerations: Maintaining a healthy lifestyle can also play a role in cancer prevention. This includes a balanced diet rich in fruits, vegetables, and whole grains, regular physical activity, avoiding tobacco, and limiting alcohol consumption. These factors can contribute to overall health and potentially lower the risk of cancer.

4. Mental Health: It is natural to feel anxious about rising CEA levels, especially with a family history of cancer. Consider discussing your concerns with a mental health professional or a support group. Managing anxiety and stress is crucial for overall well-being.

Conclusion
In summary, while your rising CEA levels are worth monitoring, they do not definitively indicate cancer, especially since they remain within the normal range. Regular follow-ups with your healthcare provider, continued screenings, and a healthy lifestyle are essential steps to take. If you have any further concerns or if your CEA levels continue to rise, do not hesitate to seek further evaluation. Early detection and proactive management are key in addressing potential health issues.
