Colorimetric Immunoassay for Detection of Tumor Markers [PDF]
International Journal of Molecular Sciences, 2010 Tumor markers are substances, usually proteins, produced by the body in response to cancer growth, or by the cancer tissue itself. They can be detected in blood, urine, or tissue samples, and the discovery and detection of tumor markers may provide earlier diagnosis of cancer and improved therapeutic intervention.
