Causes of postoperative carcinoembryonic antigen high

Carcinoembryonic antigen (CEA) is a glycoprotein produced by colorectal cancer tissue, which can cause immune response of patients. This antigen widely exists in endodermal origin of digestive system cancer, but also can exist in normal embryonic digestive tissue, of course, the content is very weak. If CEA is high, it is often found in some tumors, inflammation and degenerative diseases, including pancreatitis, alcoholic cirrhosis and other manifestations. CEA is an important indicator of postoperative follow-up in patients with colorectal cancer. If it is found to be elevated after surgery, follow-up examination should be carried out very closely.
