Tumor Marker CEA Concentration in Blood

& its Significance in Cancer Medical Diagnosis

Tumor marker CEA, stands for carcinoembryonic antigen, which is a protein highly correlated with some cancers. So CEA protein is a cancer-specific biomarker in the blood, and a high CEA level in one's blood sends a signal of certain cancers, which makes CEA protein concentration a well known tumor marker, and is one of several most important testing objects in the cancer medical diagnostic tests.

CEA protein is usually associated with cancers in the GI tract. Cancers such as colon cancer, breast cancer, lung cancer and ovarian cancer can make the level of this protein increase. Because CEA can be produce by a number of cancers, the elevation of CEA concentration in the bloodstream will prompt doctors to evaluate further for the real source. During the treatment process of a cancer, the CEA levels can be monitored to determine a reccurence before other tests would show positive.
