A carcinoembryonic antigen (CEA) test is used to check how well treatment is working in certain types of cancer, particularly bowel cancer. Carcinoembryonic antigens are proteins produced by some types of cancer. In response to the antigens, the body produces antibodies to help fight them.

Is CEA a good indicator of cancer?
A CEA value of greater than 8 ng/ml was highly suggestive of residual disease or recurrence, even when no clinical evidence was present. Approximately 90% of the patients dying from colorectal cancer showed an increase in CEA to greater than 8 ng/ml during the course of the disease.
What malignancies are high in CEA?
CEA doesn't necessarily tell you whether you have cancer and providers don't use it to screen for cancer. It instead should be used in people who've been previously diagnosed with certain types of cancer, most commonly colorectal cancer.
What is the marker for colon cancer?
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].
What are Stage 4 CEA levels?
The most common tumor marker for colorectal cancer is carcinoembryonic antigen (CEA). Blood tests for this tumor marker can sometimes suggest someone might have colorectal cancer, but they can't be used alone to screen for or diagnose cancer.
Can you live 10 years with stage 4 colon cancer?
A mean level of 102 ng/mL was reported for patients with Dukes stage D colon cancer compared with 23 ng/mL, 6 ng/mL, and 4 ng/mL for patients with stage C, B, and A colon cancer, respectively. Our study, looking only at patients with stage IV disease, used a CEA cutoff point of 275 ng/mL, which is comparatively high.
When should I be worried about CEA?
Stage IV colon cancer has a relative 5-year survival rate of about 14%. This means that about 14% of people with stage IV colon cancer are likely to still be alive 5 years after they are diagnosed. But you're not a number. No one, including your doctor, can tell you exactly how long you'll live.
Is 3.5 CEA level high?
A normal result is typically less than 2.5 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 normal CEA mean no cancer?
A normal level of CEA is less than or equal to 3 nanograms per milliliter (ng/mL). 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 CEA level is benign?
Ask your healthcare provider what your test results mean for you. CEA is measured in nanograms per milliliter (ng/mL). Normal results are 2.5 ng/mL or lower in nonsmokers. But having a normal CEA level doesn't rule out cancer.
What is the normal range for a CEA test?
Abstract. Elevated circulating CEA levels occur in patients with benign gastrointestinal and hepatic disorders. These are usually less than 10 ng/ml.
Does high CEA mean metastasis?
The normal range for CEA is 0 to 2.5 nanograms per milliliter of blood (ng/mL). If CEA levels remain elevated during treatment, the 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.
How accurate is a CEA blood test for colon cancer?
Overexpression of CEA is closely associated with liver metastasis, which is the main cause of death from colorectal cancer. CEA is widely used as a diagnostic and prognostic tumor marker in cancer patients. It affects many steps of liver metastasis from colorectal cancer cells.
What are the symptoms of Stage 1 colon cancer?
Conclusion. Results point toward a sensitivity of CEA ranging between 50 % and 80 %, and a specificity and negative predictive value above 80 %. Results on positive predictive value showed low reliability.
