What are broad spectrum tumor markers?

Carcinoembryonic antigen, CA199 and other broad-spectrum tumor markers are tumor markers that many tumors in the body will cause elevation. For example, carcinoembryonic antigen, CA199 and so on are broad-spectrum tumor markers. If the broad-spectrum tumor markers are slightly higher than normal, then there is not necessarily a malignant tumor in the body. If there is inflammation in the body, it will be slightly higher. If it is significantly higher than normal, then it is necessary to highly suspect the existence of malignant tumors in the body. However, because it is broad-spectrum, it does not indicate which part of the tumor. Therefore, it is often necessary to check one by one to find the primary site of the tumor, and then carry out the corresponding treatment.
