🚨 CANCER BLOOD TESTS: 10 BIOMARKERS YOU SHOULD KNOW ABOUT 🎗️
Can a blood test detect cancer? The answer may surprise you.
Cancer biomarkers can help doctors evaluate certain cancers, monitor treatment response, and assess whether cancer may have returned. But here’s the critical fact: a tumor marker alone cannot confirm or rule out cancer.
🧬 10 Important Cancer Biomarkers
🔬 1. Liver Cancer — Alpha-fetoprotein (AFP)
🔬 2. Ovarian Cancer — CA-125
🔬 3. Prostate Cancer — Prostate-specific antigen (PSA)
🔬 4. Colorectal Cancer — Carcinoembryonic antigen (CEA)
🔬 5. Pancreatic Cancer — CA 19-9
🔬 6. Breast Cancer — CA 15-3
🔬 7. Testicular Germ Cell Tumors — AFP and beta-hCG
🔬 8. Certain Lung Cancers — CYFRA 21-1
🔬 9. Certain Thyroid Cancers — Thyroglobulin
🔬 10. Germ Cell Tumors — AFP, beta-hCG, and other markers, depending on the tumor type
⚠️ WHAT EVERY AMERICAN SHOULD KNOW
✅ Some biomarkers are useful for monitoring specific cancers.
✅ Elevated levels can also occur in noncancerous conditions.
✅ Normal results do not always exclude cancer.
✅ Routine cancer screening should follow evidence-based recommendations based on age, personal risk, and medical history.
🇺🇸 U.S. CANCER SCREENING REMINDER
For average-risk adults, established screening recommendations cover breast, cervical, colorectal, and lung cancer for eligible individuals. Prostate cancer screening decisions should be discussed with a healthcare professional.
Don't order tumor-marker tests randomly or rely on a single result. Ask your healthcare provider which screening tests are appropriate for you.
💬 QUESTION OF THE DAY: Did you know that an abnormal tumor-marker result does not automatically mean cancer?
