What Are Tumor Markers?

1 Answer

Tumor markers are substances produced by the body in responses to cancer growth. Most tumor markers are proteins. They may be detected in blood, urine, or tissue samples. Quite a few tumor markers are now in clinical use. They are combined with other tests to help detect and diagnose some types of cancer. Some of them are linked with only one type of cancer, while others are associated with two or more cancer types. Some of the tumor markers currently used are as follows.
