Supporting Early Detection and Cancer Monitoring

Tumor marker testing measures specific substances in the blood, urine, or tissues that may be produced by cancer cells or by the body in response to cancer. These tests help in early detection, diagnosis support, treatment monitoring, and follow-up care.

What Is Tumor Marker Testing?

Tumor markers are biological molecules—such as proteins, hormones, or enzymes—associated with certain types of cancers. Tumor marker testing analyzes these markers to assist doctors in understanding the presence or progression of cancer.
