How dangerous is CEA 100?

Carcinoembryonic antigen reaching more than 100ng/ml is dangerous.

Carcinoembryonic antigen is a protein complex rich in polysaccharides and is also the most commonly used tumor marker. It has strong specificity and is of certain significance for early tumor diagnosis. In general, the normal value should be 0- 5.0 ng/ml. If it reaches 100ng/ml, it is far beyond the normal range and may indicate that the patient has malignant tumors of the digestive tract, such as colon cancer, rectal cancer, and gastric cancer. Of course, this is not absolute, and a comprehensive judgment needs to be made based on the patient's specific symptoms and other test results.

If the test finds that your carcinoembryonic antigen exceeds 100ng/ml, it is recommended not to panic too much, but you should also pay enough attention. It is very important to conduct further examinations in a timely manner, clarify the cause, and carry out targeted treatment under the guidance of a doctor.
