The full meaning of CEA is Carcinoembryonic Antigen.
Understanding Carcinoembryonic Antigen (CEA)
Carcinoembryonic Antigen (CEA) is a protein that plays a role in cell adhesion. It is naturally produced by cells in a healthy adult body, though typically in very low amounts.
According to the provided reference, CEA is described as:
- A protein produced by normal cells.
- Often overexpressed, meaning produced in much higher quantities, in certain types of cancers known as adenocarcinomas.
- Can be detected in various bodily substances and tissues.
Where is CEA Found?
CEA can be present in several locations within the body. The reference specifically mentions finding CEA in:
- Blood
- Urine
- Stool
- Other bodily fluids
- Within a tumor itself
CEA and Adenocarcinomas
Adenocarcinomas are cancers that originate in glandular tissue. The reference highlights that CEA levels can be significantly elevated in these specific cancers. While CEA can be elevated in other conditions, its overexpression is particularly noted in adenocarcinomas.
Here is a simple summary table:
| Term | Full Meaning | Description |
|---|---|---|
| CEA | Carcinoembryonic Antigen | A protein overexpressed in some cancers (adenocarcinomas). |
This protein's presence and levels are sometimes used as a marker, although the reference does not detail its clinical applications. The core meaning and nature of CEA, based on the provided text, center around its identity as a protein and its association with certain cancers.
