Detect Cancer Early with Tumor Markers
Tumor markers are substances found in the blood that can indicate the presence of cancer. These markers help doctors monitor and evaluate the likelihood of specific cancers. Below is an overview of some commonly used tumor markers:
Tumor Marker List and Standard Values
1. CEA (Carcinoembryonic Antigen)
- Detects colorectal cancer.
- Normal: < 5 ng/ml
- High: > 10 ng/ml
2. AFP (Alpha-Fetoprotein)
- Detects liver cancer.
- Normal: < 10 ng/ml
- High: > 200 ng/ml
3. PSA (Prostate-Specific Antigen)
- Detects prostate cancer.
- Normal: < 4 ng/ml
- High: > 10 ng/ml
4. B-HCG (Human Chorionic Gonadotropin)
- Detects testicular cancer.
- Normal: < 5 u/l
- High: > 5 u/l
5. B2M (Beta-2 Microglobulin)
- Detects Multiple Myeloma cancer.
- Symptoms: Chronic back pain, anemia, kidney failure, high blood calcium.
- Normal: < 2 mg/l
- High: > 2 mg/l
6. CA-125
- Detects ovarian cancer.
- Normal: < 35 u/ml
- High: > 50 u/ml
7. CA 15-3
- Detects breast cancer.
- Normal: < 40 u/ml
- High: > 60 u/ml
8. CA 19-9
- Detects pancreatic cancer.
- Normal: < 35 u/ml
- High: > 100 u/ml
9. CA 72-4
- Detects gastric cancer.
- Normal: < 6 u/ml
- High: > 30 u/ml

Things to know about Tumor Marker testing
- Certain tumor markers may be elevated in non-cancerous conditions, such as chronic inflammation or liver disease.
- Some cancers, especially in the early stages, may not show abnormal Tumor Marker values.
- Different cancers may produce similar tumor markers, making diagnosis based on multiple factors.
Recommendations
- You should consult your doctor for further examination if you find abnormally high Tumor Marker values.
- Use Tumor Marker as an additional tool to monitor treatment results and repeat examination when in doubt.
