What causes CEA to rise? The most frequent cancer which causes an increased CEA is cancer of the colon and rectum. 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 a CEA of 10 mean?
Benign disease does not usually cause a CEA increase over 10 ng/ml. The main use of CEA is as a tumor marker, especially with intestinal cancer. The most common cancers that elevate CEA are in the colon and rectum. Others: cancer of the pancreas, stomach, breast, lung, and certain types of thyroid and ovarian cancer.
How fast does CEA increase?
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.
Does CEA increase with age?
CEA levels increased with age. related to age in smokers and non- smokers. their higher mean age (Table 1).
Is CEA a reliable tumor marker?
Doctors don’t use the CEA test to make a first-time diagnosis of cancer. This test isn’t an accurate way to screen for it because many other diseases can cause the levels of this protein to rise. And some people with cancer don’t have high CEA levels.
What does a CEA blood test detect?
The carcinoembryonic antigen (CEA) test measures the level of CEA in the blood. CEA is a protein normally found in the tissue of a developing baby in the womb. The blood level of this protein disappears or becomes very low after birth. In adults, an abnormal level of CEA may be a sign of cancer.
How accurate is CEA blood test?
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 %.
How can CEA be reduced?
Thus, we suggest that exercise for 2-3 days per week decreases the expression of CEA and improves body condition, without loading fatigue or stress, which may contribute to preventing cancer in the elderly women.
Can CEA go up and down?
However, serum CEA levels fluctuate over time even in the same individuals. In some patients, the serum CEA level becomes positive in the absence of recurrence. In other patients who have positive serum CEA levels at initial surgery, the level becomes negative at the time of recurrence.
Can inflammation cause CEA to rise?
Oxaliplatin has been shown to cause an inflammatory response which appears to be one of the mechanisms of toxicity and high CEA levels have been correlated with increased inflammation.
How reliable is CEA test?
Table 1
| Final CEA measurement (95% CI) | All CEA measurements (95% CI) | |
|---|---|---|
| Specificity | 97.5% (95.5–98.6%) | 93.3% (90.6–95.3%) |
| Positive predictive value | 81.0% (68.7–89.4%) | 61.9% (50.6–72.1%) |
| Negative predictive value | 89.8% (86.8–92.2%) | 89.6% (86.5–92.0%) |
| Positive likelihood ratio | 19.5 (10.8–35.3) | 7.5 (5.1–11.0) |

Can CEA go down?
Carcinoembryonic Antigen, also called CEA, is a protein that may be elevated in many colorectal cancer patients and is detected in the blood. CEA levels are expected to go down in patients who have had surgery to remove their tumor. An elevated CEA may indicate a recurrence of your cancer.
What is a bad CA 125 level?
In most healthy women the level of CA125 is usually less than 35. However, some women do have a naturally high level of CA125 in their blood. The level of CA125 in the blood can rise for many reasons which include endometriosis, menstruation, ovarian cysts and, sometimes, ovarian cancer.
How accurate is a CEA blood test?
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 %.
What happens if tumor markers are high?
High tumor marker levels can be a sign of cancer. Along with other tests, tumor marker tests can help doctors diagnose specific types of cancer and plan treatment. Tumor marker tests are most commonly used to do the following: Learn if a person has cancer.
What is a normal CEA tumor marker?
A normal result is less than 5 nanograms per milliliter. Results might vary between labs. A higher-than-normal CEA level that increases over time might signal that your cancer has grown or has come back after treatment. But high levels of CEA do not always mean you have cancer.
Does Covid increase CEA levels?
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 a CEA blood test tell you?
The carcinoembryonic antigen (CEA) test measures the level of CEA in the blood. CEA is a protein normally found in the tissue of a developing baby in the womb. The blood level of this protein disappears or becomes very low after birth. In adults, an abnormal level of CEA may be a sign of cancer.
What does CEA mean in a blood test?
Carcinoembryonic antigen (CEA) is a protein that is primarily associated with certain types of cancer. The most common way to measure CEA is through a blood test, although other bodily fluids may be tested as well.
Can stress raise CEA levels?
Our findings clearly indicated that immobilization stress results in enhanced serum CEA level whether the stress is acute or chronic. Consistent with our finding, there are reports suggesting that stress can increase tumor growth and tumor marker expression [26, 27].
How often should CEA test be done?
The National Comprehensive Cancer Network, for example, recommends that people who are treated for stage II or III colon or rectal cancer have CEA testing every 3 to 6 months for 2 years and then every 6 months for 3 additional years, plus CT scans every 6 to 12 months for 5 years.
Can inflammation increase CEA levels?
Oxaliplatin has been shown to cause an inflammatory response, which appears to be one of its mechanisms of toxicity, and a raised CEA level has been correlated with increased inflammation (17).
Can arthritis cause CEA to rise?
In conclusion, the levels of serum tumor markers, CEA, CA 19-9, CA125 and CA 15-3 are frequently increased in patients with RA. Their levels can be elevated even in well controlled disease.
Can exercise increase CEA levels?
As results, CEA was significantly decreased in the exercise groups, with the lowest values in 2-3E group. In contrast, AFP, RBC and WBC were not significantly changed. CEA is an oncofetal glycoprotein that is overexpressed in adenocarcinomas.
