What is a normal CEA tumor marker?

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.

What is CEA in 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.

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.

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.

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 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 %.

Does CEA increase with age?

CEA levels increased with age. related to age in smokers and non- smokers. their higher mean age (Table 1).

What is the normal range for CEA blood levels?

The normal range is 0 to 2.5 ng/mL (0 to 2.5 µg/L). In smokers, slightly higher values may be considered normal (0 to 5 ng/mL, or 0 to 5 µg/L).

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.

How do you lower CEA levels?

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 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].

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.

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.

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.

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.

What can raise 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 indicates cancer.

How do I lower my CEA levels?

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.

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 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 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.
