Summary

This study is testing whether a simple blood test can help rule out breast cancer in women who had a suspicious mammogram. About 75% of women called back for extra testing turn out to be fine, but they still go through stressful and unnecessary procedures. The goal is to use blood biomarkers to identify low-risk women and avoid those extra mammograms and biopsies. The study will enroll 1,200 women from the Danish breast cancer screening program.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: blood-based biomarker test
What this could lead to: If successful, this could make breast cancer screening more accurate and reduce the need for additional, often unnecessary, mammograms and biopsies.
What could go wrong: This is an early-stage study focused on correlation, not a proven diagnostic test. The blood test may not be accurate enough to replace current procedures, and results may not apply to all populations.
