Tumor Marker Tests

Tumor marker tests measure specific substances in the blood, urine, or tissues that are produced by cancer cells or by the body in response to cancer. These markers can help in diagnosing certain cancers, monitoring treatment effectiveness, and checking for recurrence. It's important to note that elevated tumor markers are not exclusive to cancer and can be influenced by other conditions. Therefore, these tests are used alongside other diagnostic tools rather than as definitive proof of cancer. They provide valuable information but are part of a broader clinical assessment.
