What is CEA (Carcinoembryonic Antigen)
CEA (Carcinoembryonic Antigen) is a protein produced by the cells of a developing fetus. Normally, CEA levels are very low or undetectable in adults. However, in certain types of cancer, such as colorectal cancer, lung cancer, and pancreatic cancer, CEA levels may rise.
What Does an Elevated CEA Level Mean?
An elevated CEA level can be a sign of cancer, but it’s important to remember that it’s not a definitive diagnosis. Other conditions, such as liver disease, heavy smoking, and certain inflammatory bowel diseases, can also cause elevated CEA levels.
Symptoms of Cancer (General):
- Unexplained weight loss

- Sores that don’t heal

If you experience any of these symptoms, it’s important to consult your doctor for further evaluation.
Remember: Early detection is key to successful cancer treatment.
Regular check-ups and screenings are crucial, especially for individuals with risk factors.
