What does it mean when your CEA levels are low?
To monitor cancer treatment: If CEA levels are decreasing it usually means a tumor is responding to treatment, whereas if levels are increasing, it may mean the tumor is progressing. CEA is often ordered as a baseline test at the beginning of cancer treatment for this reason.
What causes Elevated CEA levels?
There are a number of both benign and cancerous conditions that may cause an elevated CEA level. Certainly, there are many exceptions to this general rule. For example, a CEA over 20.0 may be due to an early stage cancer plus a benign condition such as hypothyroidism in a person who smokes.

Can CEA levels go up and down?
Serum CEA levels fluctuate over time in healthy individuals, and the intraindividual variation has been reported to be about 30% [19].
What does it mean when your CEA drops?
A low CEA level indicates a small tumor that hasn't spread elsewhere in the body. A high CEA level may correspond to a larger tumor and/or cancer that has spread—or metastasized—to one or more locations away from the original site.
What can falsely elevated CEA?
Diabetes, smoking, chronic obstructive pulmonary disease, and colonic polyps were considered as causes of false elevation. The false-positive rates of CEA according to level were as follows: 5.1–10.0 ng/mL, 99.5%; 10.1–15.0 ng/mL, 87.2%; 15.1–20.0 ng/mL, 100.0%; >20.0 ng/mL, 33.3%.

conducted a study of 136 mCRC patients where they tested patient CEA levels every 4 weeks and defined CEA responders as mCRC patients with a greater than 50% drop in CEA after more than 4 weeks. That study demonstrated the usefulness of CEA monitoring in determining the response to chemotherapy.
How quickly can CEA levels rise?
Two distinct patterns of CEA rise were observed: a 'fast' rise in which serum concentrations reached 100 microgram/l within 6 months of the first elevation and a 'slow' rise in which concentrations remained less than 75 microgram/l for at least 12 months.
Can stress cause tumor markers to rise?
A 2019 study, for example, showed that stress hormones can increase the number of pro-tumor immune cells in tumors. That could mean that stress not only wakes up dormant tumor cells but also provides the right environment for them to grow, Dr. Hildesheim explained. “It's the worst of both worlds,” he said.
What can affect CEA levels?
These include cancers of the colon and rectum, prostate, ovary, lung, thyroid, or liver. High CEA levels may also be a sign of some noncancerous conditions, such as cirrhosis, noncancerous breast disease, and emphysema.
Does inflammation affect CEA levels?
Carcinoembryonic antigen (CEA), a serological marker of malignant tumors, demonstrates a modest increase under nonmalignant conditions such as aging and smoking. Also, recent study results suggested that serum CEA levels may be related to insulin resistance or low-grade inflammation.

Sensitivity of CEA ranged from 17.4 % to 100 %, specificity ranged from 66.1 % to 98.4 %, positive predictive value ranged from 45.8 % to 95.2% and negative predictive value ranged from 74.5 % to 100 %.

SARS-CoV-2 infection might be another cause of CEA elevation, with nearly 20% of patients experienced transient and marked CEA increment during COVID-19 pneumonia. The false-positive results of CEA elevation might have clinical significance for patients with colorectal cancer.
What does it mean when your CEA is elevated?
Elevated levels of CEA occur when the CEA is higher than 3 ng/mL. These levels are considered abnormal. People with many types of cancers can have levels that are higher than 3 ng/mL. If you have values that are that high, it doesn’t mean you have cancer. Other reasons can cause levels higher than 3 ng/mL.
Why do doctors use CEA?
Your doctor might also use the CEA test to help determine if a cancer has come back, or recurred, after finishing treatment. A CEA test is most useful after a diagnosis of a type of cancer that’s known to produce CEA. Not all cancers produce CEA. Increased levels of CEA may be found in the following cancers:

Most healthy people have levels below this amount. CEA levels will generally return to normal between one and four months after the cancer has been successfully removed.
What does it mean when you have a high CEA?
A high amount of CEA in your body after a cancer treatment or surgery suggests the cancer is not gone. It may also mean that the cancer has spread to other parts of your body.

As cancer cells die, CEA is released into the bloodstream and levels can remain elevated for a few weeks after treatment, even if a tumor is responding well. For example, CEA results may be very high during and after chemotherapy.

Why do we need a CEA test?
CEA is often ordered as a baseline test at the beginning of cancer treatment for this reason.

Colorectal cancer patients whose CEA blood tests rise at the beginning of chemotherapy and then fall ( CEA flare) do better than patients with a consistently rising CEA. CEA flares don’t necessarily predict worsening cancer.
Purpose of The Test
Cancers Monitored with Cea
- CEA is most commonly used with digestive tract cancers.3It may also be used as a tumor marker test to monitor a number of different cancer types, including: 1. Colorectal cancer 2. Pancreatic cancer 3. Stomach cancer (gastric cancer) 4. Lung cancer 5. Breast cancer 6. Ovarian cancer 7. Thyroid (medullary) cancer 8. Bladder cancer 9. Head and neck cancer 10. Cervical cancer 11.

The Test
- The CEA test may be done in the hospital or in a clinic. The test is often run on a blood sample, but may also be run on fluid obtained from the central nervous system (via a lumbar puncture or spinal tap), from the pleural cavity (via thoracentesis), or from the peritoneal cavity (via paracentesis). The description below refers to having the test done in the most common way: th…
Interpreting Results
- A single CEA test may give doctors some idea about what is happening in your body. The test should be repeated if it is abnormal to verify the result.
Summary
- A CEA test can be useful in monitoring cancer treatment, but it's important to note that it should not be used alone and is most helpful when looking at changes in CEA levels over time rather than as a single value. Since CEA levels can take some time to decrease during colon cancer treatment, a health care provider will consider the whole picture rather than make treatment deci…
A Word from Verywell
- CEA levels can help your health care providers monitor cancer treatment and predict prognosis. However, the prognosis of many cancers is changing with newer treatments and technology. Keep in mind that currently available statistics don't necessarily reflect those improvements.
