CEA (Carcinoembryonic Antigen) in Body Fluid

The Carcinoembryonic Antigen (CEA) test in body fluid is an important tool used to diagnose and monitor certain types of cancers. CEA is a protein that can be found in various parts of the body but is usually produced during fetal development. Production usually halts before birth, and hence, the presence of CEA in adults could be indicative of cancer.

CEA levels can rise in certain cancers, making it a useful biomarker, especially in colorectal cancer. However, it's important to note that CEA can also rise in non-cancerous conditions, and not all types of cancers cause an increase in CEA levels. This guide will answer frequently asked questions about the CEA test in body fluids.
