Tumor Markers
Tumor markers are substances found in blood, tissues, or other body fluids that can help identify cancer. They're like warning signs that doctors and laboratory professionals look for during patient testing. Think of them as clues that help healthcare teams detect and monitor cancer. Some common examples include PSA for prostate cancer and CA-125 for ovarian cancer. Healthcare professionals use these markers to screen for cancer, check if treatments are working, or watch for signs that cancer might be returning. While not every cancer produces markers, and some non-cancerous conditions can raise marker levels, they're an important tool in cancer diagnosis and monitoring.
