Order Cancer & Tumor Marker TestsCancer and tumor marker tests are blood tests that measure substances produced by certain cancers or by the body in response to cancer. They are used alongside imaging, biopsies, and clinical exams rather than as stand-alone diagnostic tools, and their results are interpreted in the context of a person's history and other findings.
About Cancer & Tumor Marker Tests in Hercules
Tumor markers are measurable substances that can be elevated in some cancers, but they are not specific to a single disease.
A tumor marker is typically a protein, hormone, antigen, or enzyme that can be detected in blood or other body fluids. Some markers are produced directly by tumor cells, while others reflect the body's response to a malignancy. Because benign conditions and normal tissues can also produce these substances, an abnormal level does not by itself confirm cancer, and a normal level does not rule it out.
Different markers are associated with different cancer types. Examples include prostate-specific antigen for prostate tissue, carcinoembryonic antigen for several gastrointestinal and other cancers, CA-125 for ovarian and related tissues, alpha-fetoprotein for liver and germ cell tumors, and CA 19-9 for pancreatic and biliary tract cancers. Some tests measure a single marker, while panels combine several markers to improve clinical usefulness in specific situations.
Clinicians order tumor marker tests for several purposes: to help evaluate a suspicious finding, to estimate prognosis, to monitor response to treatment, or to watch for recurrence after therapy. Results are compared with reference ranges established by the performing laboratory, and trends over time are often more informative than a single value. Interpretation always belongs to the treating clinician, who considers the marker alongside imaging, pathology, and the patient's overall condition.
