CEA 7.7 is more serious and you should go to the hospital immediately for appropriate examination. CEA is carcinoembryonic antigen (CEA), an acidic glycoprotein with human embryonic antigen characteristics, which exists on the surface of cancer cells differentiated from endodermal cells and belongs to structural proteins of cell membranes.The normal value of CEA is <5.0ng/ml.Clinically, ≥5.0ng/ml is called elevated CEA. Elevated CEA can be seen in: digestive tract tumors such as colorectal cancer, gastric cancer, hepatocellular carcinoma, pancreatic cancer, etc.; smoking, pregnancy, diabetes mellitus, inflammatory bowel disease, cirrhosis of the liver, pancreatitis, rectal polyps, etc. CEA is not a specific marker for malignant tumors, and plays an auxiliary role in clinical diagnosis. Patients with CEA7.7 should immediately go to the hospital for appropriate examination to clarify the diagnosis.
