What is a good CEA result?

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.

Can CEA be elevated 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 do CEA levels indicate?

CEA is a type of tumor marker. Tumor markers are substances made by cancer cells or by normal cells in response to cancer in the body. 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.

Does CEA increase with age?

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

Can CEA rise after chemo?

Median rise in CEA from baseline was 263% (range 24-632%). An initial rise of CEA during chemotherapy in colorectal cancer patients may therefore not always indicate progression of disease but may be a transient CEA surge in patients responding to chemotherapy.

What is a good CEA level?

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 the normal range for tumor markers?

Tumor Marker reference range. The normal range for tumor marker 15-3 is less than or equal to 30 units per milliliter.

What is an elevated cancer marker?

An elevated level of a tumor marker can indicate cancer; but, there can also be other causes of the elevated tests. Tumor markers can be produced directly by the tumor or by non-tumor cells as a response to the presence of a tumor. Most tumor markers are tumor antibodies, but not all tumor antibodies can be used as tumor markers.

What is a high CEA?

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.
