What level of CEA indicates cancer?

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.

What is elevated 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.

What does a CEA level of 8 mean?

It is concluded that a rise in CEA to greater than 8 ng/ml indicates with high degree of certainty relapse or disease progression in colorectal cancer patients. CEA is not a reliable indicator of clinical response to chemotherapy, and an increase in the CEA level is of little prognostic value concerning survival.

What can cause high CEA levels?

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 is a normal CEA tumor marker?

Tumor marker, CEA: Carcinoembryonic antigen (CEA) is a protein found in many types of cells but associated with tumors and the developing fetus. CEA is tested in blood. The normal range is <2.5 ng/ml in an adult non-smoker and <5.0 ng/ml in a smoker.

What is normal CEA range?

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).

What is a normal CEA range?

Normal Results 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 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?

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.

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 causes Elevated CEA level?

While high CEA levels can indicate that cancer is present, they can also point to other medical conditions. Kidney failure, inflammatory bowel disease, cirrhosis of the liver, pancreatitis, and peptic ulcer disease are all known to cause elevated CEA levels.

What is a normal value for CEA?

The normal value for those taking a CEA, or carcinoembryonic antigen, blood test is 0 to 2.5 micrograms per liter, according to MedlinePlus. For smokers, the normal value range is 0 to 5 micrograms per liter.

What is CEA lab result?

A Carcinoembryonic Antigen (CEA) Test is a tumor marker test that measures the amount of a protein called Carcinoembryonic Antigen (CEA), in blood. CEA is a type of protein normally produced by the tissues of a developing fetus. In adults, detection of elevated levels of CEA in blood may indicate cancer of the large intestine (colon, rectum).

What is a high CEA level?

A very high CEA level (above 20 ng/ml) is an indication of highly spread cancer. CEA tests are mainly used to measure the success of cancer surgery. An elevated CEA level is likely to fall to normal after a successful surgery. Rising CEA levels is an indication of progressing or recurrence of cancer.
