Order Cancer & Tumor Marker TestsCancer and tumor marker tests are blood-based assays that measure specific proteins, hormones, or other substances produced by certain tumors or by the body in response to cancer. These markers can be useful for monitoring a known diagnosis, assessing response to treatment, or detecting recurrence, but they are rarely used alone to screen for or diagnose cancer.
About Cancer & Tumor Marker Tests in Walnut
Tumor markers are measurable substances whose levels may rise in the presence of particular cancers, though many benign conditions can also affect them.
A tumor marker is typically a protein, hormone, enzyme, or other molecule that can be detected in blood, urine, or tissue. Some markers are produced directly by cancer cells, while others are produced by normal cells in response to a tumor. Because no marker is perfectly specific to cancer, results are interpreted alongside imaging, biopsy findings, and clinical history.
Common examples include prostate-specific antigen (PSA) for prostate tissue, carcinoembryonic antigen (CEA) for certain colorectal and other cancers, CA-125 for ovarian and related conditions, CA 19-9 for pancreatic and biliary tract disease, alpha-fetoprotein (AFP) for liver and germ cell tumors, and human chorionic gonadotropin (hCG) for germ cell tumors. Each marker has its own reference range and clinical context.
Collection is usually a standard venipuncture blood draw, though some markers may be measured in urine or other body fluids. Results are reported with the laboratory's reference interval and units, and a single value is generally less informative than a pattern of values over time. Turnaround for most tumor marker assays is one to three business days, depending on the specific marker and the laboratory's workflow.
