Common "Cea" queries answered by top doctors | iCliniq


CEA stands for a carcinoembryonic antigen, a naturally occurring protein in the tissues of the developing fetus, which then reduces and becomes very minimal after birth. It is measured by a CEA test, for which a blood sample is required. Cancers of the breast, urinary tract, reproductive organs, lung, colon, pancreas, and thyroid show higher levels of CEA. In addition, it can also be increased due to smoking, liver disorders, gallbladder problems, inflammatory bowel disease, pancreatitis, gastritis, lung infection, etc.
