A blood test for breast cancer? the future of screening may be in your vein
NCT ID NCT04495244
First seen Aug 19, 2026 · Last updated Aug 20, 2026 · Updated 1 time
Summary
This study is testing a new blood test, called Syantra DX Breast Cancer, to see if it can accurately identify the presence of breast cancer. The test looks for specific genetic markers in the blood that may indicate cancer. Researchers will compare the test results with standard imaging and biopsy results from 10,000 women to determine its accuracy. If proven reliable, this could offer a less invasive and more accessible screening option for breast cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Syantra DX Breast Cancer blood test
- What this could lead to
- If successful, this blood test could become a routine, less invasive screening tool to catch breast cancer earlier, potentially improving survival rates.
- What could go wrong
- The test is still being validated in a large, real-world setting. It may not be accurate enough to replace mammograms, and false positives or negatives remain possible.
