Can a single breast MRI at 45 catch cancer earlier?
NCT ID NCT07878377
First seen Oct 16, 2026 · Last updated Oct 16, 2026
Summary
Researchers in the Netherlands are studying whether a one-time breast MRI scan at age 45 can detect breast cancer early in women who are not yet in routine screening. About 2,600 women will receive a high-resolution MRI and complete questionnaires about their reasons for joining, their cancer-related worry, and their experience. The study also tracks the cost per cancer found and follows a subset of women one year later to see how screening affects their health beliefs.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a one-time breast MRI screening scan
- What this could lead to
- If it works, this could point toward a new way to spot breast cancer earlier in women around age 45, when standard mammograms are not routine. It could also help health systems weigh the costs and benefits of MRI-based screening.
- What could go wrong
- MRI can flag harmless findings that lead to extra tests and anxiety, called false positives. A single scan at one age may miss cancers that develop later, and the study does not yet show whether finding cancer earlier saves lives.
