1. doll_face : Carcinoembryonic antigen (CEA) is a protein normally found in the tissue of a developing baby in the womb. Blood levels of this protein disappear or become very low after birth. In adults, an abnormal amount of CEA may be a possible sign of cancer. Smoking may increase CEA levels. If you smoke, your doctor may tell you to avoid doing so for a short time before the test. This test is not an accurate way to diagnose any type of cancer, and high levels can be found in people without cancer. This test's most accurate and important use is to see how well a person responds to cancer treatment. The normal range is 0 to 2.5 micrograms per liter (mcg/L). Normal value ranges may vary from lab to lab. In smokers, slightly higher values may be considered normal. What Abnormal Results Mean Higher-than-normal levels may be due to: Breast cancer Cancers of the reproductive and urinary tracts Cholecystitis Cirrhosis and other liver disease Colon cancer Diverticulitis Heavy smoking Inflammatory bowel diseases (such as ulcerative colitis) Lung cancer Lung infection Pancreatic cancer Pancreatitis Peptic ulcer Thyroid cancer
