Question: Does elevated CEA always mean cancer?

Can CEA be high without cancer?

Can CEA be high without having 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.

What is considered a high CEA level?

Levels of CEA higher than 20 ng/mL are considered very high. If you have CEA levels this high and you also have symptoms of cancer, it strongly suggests the cancer has not been removed successfully after treatment. It may also suggest that the cancer has metastasized, or spread, to other parts of your body.

What can cause high CEA levels?

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.

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 kind of cancer does CEA detect?

In addition to colon and rectal cancer, CEA testing may be done in relation to the following types of cancer: Breast cancer. Lung cancer. Thyroid cancer.

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 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.

Do CEA levels increase with age?

This study showed that elderly people in their 80s, in apparent good health, had higher levels of CEA (3.0 +/- 1.4 ng/ml) than younger people. These levels were shown to be significantly increased in a large number of non-malignant diseases.

What does a CEA level of 8 mean?

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.

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.

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.
