“Tumor Marker” (also known as “Cancer Index”) as a cancer diagnostic tool
Tumor markers, also called “cancer markers,” are substances (usually proteins) produced by cancer cells or normal cells in response to cancer. Tumor markers are commonly found in blood, urine, stool or tissue samples from cancer patients. Tumor markers provide important information for diagnosing cancer, predicting treatment response, monitoring treatment effectiveness, and detecting recurrence. This article will explore the role of tumor markers in cancer diagnosis, their advantages and limitations, and what to expect during testing.
