CARCINOEMBRYONIC ANTIGEN Meaning and
Definition
-
Carcinoembryonic antigen (CEA) is a glycoprotein that is typically produced by developing gastrointestinal tissues during fetal development but should not be present in healthy adults. It serves as a tumor marker, meaning that its presence or levels in the body can indicate the presence of certain types of cancers, particularly gastrointestinal malignancies such as colorectal, pancreatic, and gastric cancer.
CEA is classified as a glycoprotein because it consists of both carbohydrates and proteins. It is primarily produced by cells that line the gastrointestinal tract, such as those in the colon and rectum, and can be found in other tissues as well, including the lungs and liver.
Tests that measure CEA levels are commonly used in clinical practice to help diagnose and monitor the progression of cancer, evaluate the effectiveness of treatment, and detect potential recurrence of the disease. However, CEA is not specific to cancer and can be elevated in non-cancerous conditions, such as inflammatory bowel disease, liver disease, and smoking.
While CEA tests can be a useful tool in cancer management, they are not definitive diagnostic tests on their own and should be interpreted in conjunction with other clinical findings and imaging studies. Additionally, CEA levels can vary greatly between individuals, so a single test result may not provide conclusive information. Regular monitoring of CEA levels over time can help healthcare professionals get a better understanding of an individual's cancer status and response to treatment.

Etymology of CARCINOEMBRYONIC ANTIGEN
The word "Carcinoembryonic Antigen" (CEA) has a Latin and Greek origin.
The term "Carcino" originates from the Greek word "karkinos" (καρκίνος), meaning "crab". This term was used by the Greek physician Hippocrates to describe tumors, as they often have crab-like extensions. Over time, "karkinos" evolved into "cancer" in English, which refers to malignant growths.
"Embryonic", on the other hand, comes from the Latin word "embryo", derived from the Greek word "embruon" (ἔμβρυον). This term refers to the early stages of development in an organism, specifically from conception to the end of the eighth week of pregnancy in humans.
