What Are Tumor Markers?
Tumor markers are substances produced by cancer cells or by normal cells in response to cancer. PSA (Prostate-Specific Antigen) is primarily used for prostate cancer screening, CEA (Carcinoembryonic Antigen) helps monitor colorectal and other cancers, CA 125 is associated with ovarian cancer, and CA 19-9 is linked to pancreatic and other gastrointestinal cancers.
These markers are crucial for cancer screening, diagnosis, monitoring treatment response, and detecting recurrence. Our AI-powered report interpreter online analyzes these values in clinical context, providing comprehensive risk assessment and evidence-based insights for informed healthcare decisions.
PSA: The Prostate Health Guardian
PSA is the most widely used biomarker for prostate cancer screening in men over 50. Elevated levels may indicate prostate cancer, but can also be caused by benign conditions like prostate enlargement or infection.
- Screening tool: Primary marker for prostate cancer detection
- Age-specific ranges: Normal values increase with age
- Trend monitoring: Changes over time more important than single values
- PSA velocity: Rate of PSA increase helps assess cancer risk
- Treatment monitoring: Tracks response to prostate cancer therapy
CEA: The Versatile Cancer Monitor
CEA is elevated in several cancer types, particularly colorectal cancer. It's primarily used for monitoring treatment response and detecting recurrence rather than initial screening.
Primary Uses
Monitoring colorectal cancer treatment, detecting recurrence, staging assessment
Associated Cancers
Colorectal, lung, breast, pancreatic, stomach cancers
CA 125 & CA 19-9: Specialized Screening Markers
CA 125 (Ovarian Cancer)
- Primary ovarian cancer marker
- Monitoring treatment response
- Detecting recurrence
- Can be elevated in benign conditions
CA 19-9 (Pancreatic Cancer)
- Pancreatic cancer monitoring
- Treatment response assessment
- Prognosis indicator
- Also elevated in bile duct cancers
