What is Tumor Markers?
Tumor Markers
Tumor markers are substances produced by cancer cells or by the body in response to cancer. They are used in diagnosing cancer, monitoring treatment, and checking for recurrence.
Overview
Tumor markers are often proteins or other molecules found in the blood, urine, or tissues that can indicate the presence of cancer. Doctors use these markers to help diagnose cancer, determine how advanced it is, and decide on the best treatment options. For example, the prostate-specific antigen (PSA) test measures a specific tumor marker to help detect prostate cancer in men. When a tumor is present, it can release specific markers into the bloodstream. Healthcare providers can measure these levels through blood tests, which helps them understand whether a patient is responding to treatment or if the cancer has returned. This process connects to diagnostics and imaging, as tumor markers can provide essential information that supplements imaging tests like CT scans or MRIs. Understanding tumor markers is crucial for effective cancer management. They can give insights into the type of cancer a person has and how aggressive it may be. By tracking these markers over time, doctors can tailor treatments to improve outcomes and monitor the effectiveness of therapies.
