What can cause Elevated CEA levels?
Benign conditions which can elevate CEA include smoking, infections, inflammatory bowel disease, pancreatitis, cirrhosis of the liver, and some benign tumors in the same organs in which an elevated CEA level indicates cancer. What does it mean if you have a high CEA blood level?
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.
Can CEA and CA 19-9 levels be elevated without cancer?
Yes, elevations in CEA and CA 19-9 levels may occur in patients without cancer. In fact studies suggest that falsely elevated levels may occur in up to 50% of colon cancer patients post treatment leading to unnecessary anxiety and testing. Can CEA levels increase with chemotherapy treatment?
Is it common for CEA levels to rise during chemotherapy?
As long as I understood, rising CEA level during chemotherapy is common. I like to hear your experience. Welcome to our forum, sahm. I'm sorry to hear that your mother was diagnosed with colon cancer stage 3B and that you are, understandably, worried about what her blood tests might mean.
What does it mean when your CEA levels go down?
Low CEA levels could mean a tumor is small and hasn't spread to other parts of your body. But certain types of cancer don't shed as much CEA, especially those limited to certain areas such as your brain, blood CEA tests may show low CEA levels. This is where your physician considers imaging techniques such as MRI.
What can cause CEA levels to rise other than cancer?
Higher than normal CEA level alone cannot diagnose a new cancer. Further testing is needed. An increased CEA level may also be due to: Liver and gallbladder problems, such as scarring of the liver (cirrhosis), or gallbladder inflammation (cholecystitis)
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%.
Can you have a high CEA and not have cancer?
A high level of CEA can be a sign of certain types of cancers. 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.
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 level of CEA indicates cancer?
The normal range for CEA is 0 to 2.5 nanograms per milliliter of blood (ng/mL). If CEA levels remain elevated during treatment, your treatment may not have been as successful as hoped. Anything greater than 10 ng/mL suggests extensive disease, and levels greater than 20 ng/mL suggest the cancer may be spreading.
Can inflammation cause CEA levels to rise?
For patients with colonic adenocarcinoma receiving adjuvant chemotherapy, any rise in CEA level should prompt thorough evaluation for disease recurrence; however, in the absence of disease, it should be noted that inflammatory changes could be the trigger of a CEA rise.
How reliable are CEA markers?
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.
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.

Yes, elevations in CEA and CA 19-9 levels may occur in patients without cancer. In fact studies suggest that falsely elevated levels may occur in up to 50% of colon cancer patients post treatment leading to unnecessary anxiety and testing.
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.
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.

What causes elevated CEA levels?
However, there are a number of benign conditions that may lead to elevations in serum CEA level including cigarette smoking, pancreatitis, biliary obstruction, peptic ulcer disease, and hypothyroidism , but the extent of elevation is substantially less, and it is rare to see an elevation of >10 ng/ml in this context.
What is the meaning of CEA?
Introduction. Carcinoembryonic antigen (CEA) is an oncofetal glycoprotein that is normally expressed by mucosal cells. It is overexpressed by a variety of malignancies. Although it is most commonly associated with colorectal cancer, it can also be elevated in other malignancies such as breast, liver, stomach, and pancreas [1].

Carcinoembryonic antigen (CEA) has been shown to be associated with tumor burden in patients with colorectal cancer. However, it is also elevated to a significant degree in a number of other malignant and non-malignant conditions. We report a case of reversible CEA elevation in a patient using lithium for bipolar disorder.
Does lithium increase iodine?
Lithium increases intrathyroidal iodine content, inhibits the coupling of iodotyrosine residues to form iodothyronines (thyroxine [T4] and triiodothyronine [T3]), and inhibits the release of T4 and T3 in therapeutic doses [6].
Does orlistat cause elevated CEA?
The underlying pathophysiology by which orlistat led to CEA elevation was unclear. Theoretically, orlistat's inhibition of pancreatic lipase can lead to colitis from unabsorbed lipids which can lead to an elevated CEA level. However, this does not appear to be a similar pathway for lithium.
Why do we draw CEA?
Some of these include: 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.
How long does CEA stay elevated after cancer treatment?
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.
