Order Cancer & Tumor Marker TestsCancer and tumor marker tests are laboratory assays that measure specific substances in the blood or other body fluids. These substances, often proteins, hormones, or enzymes, can be produced by normal cells as well as by some cancer cells. Because marker levels can rise for reasons unrelated to cancer, these tests are generally used alongside imaging, biopsy, and clinical evaluation rather than as stand-alone diagnostic tools.
About Cancer & Tumor Marker Tests in Walnut
Tumor markers are biological signals that can be quantified to support oncologic assessment and monitoring.
Tumor markers are substances that may be detectable in blood, urine, or tissue. Some are produced directly by tumor cells, while others are produced by normal cells in response to a tumor or other conditions. Common examples include prostate-specific antigen (PSA), carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP), CA-125, CA 19-9, and CA 15-3. Each marker has a different tissue association and clinical purpose.
A single marker result is rarely sufficient to confirm or exclude cancer. Levels can be influenced by benign conditions such as inflammation, infection, liver disease, or smoking, and some cancers do not produce elevated marker levels at all. For these reasons, marker results are interpreted in context with a person's history, physical examination, imaging studies, and, when indicated, tissue biopsy.
Tumor marker tests are most often used to monitor a known diagnosis over time, to assess response to treatment, or to detect recurrence after therapy. They may also be used in certain screening or risk-assessment settings when a marker has been validated for that purpose. Collection typically involves a standard blood draw, and results are usually reported within one to three business days. Preparation depends on the specific marker being measured, so following the laboratory's instructions is important.
