Is CEA 6 a cancer alert?

Carcinoembryonic antigen 6μg/L

is a broad spectrum tumor marker, which can be expressed in a variety of tumors, especially in colorectal cancer, lung cancer and gastric cancer. The normal reference value of carcinoembryonic antigen is 0-5μg/L, while 6μg/L is beyond this range, indicating that the index is high and the possibility of the above cancers needs to be vigilant. However, carcinoembryonic antigen is not specific. In addition to cancer, it may also be associated with benign lesions such as pancreatitis, gastrointestinal polyps and colitis, so there is no need to worry too much. If you are not confident or suspicious, you can further confirm the diagnosis through endoscopic examination and pathological examination.
