Magnetic seeds vs radioactive dye: which is better for breast surgery?
NCT ID NCT05942092
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks back at 1,400 women who had breast-conserving surgery for non-palpable breast lesions. It compares two methods used to find the lesion during surgery: injecting a radioactive substance (ROLL) or placing a tiny magnetic seed. The goal is to see which technique leads to cleaner surgical margins and fewer repeat operations.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If one technique proves superior, it could guide surgeons toward a more effective method for removing non-palpable breast lesions with fewer repeat surgeries.
- What could go wrong
- This is a retrospective study, not a controlled trial, so results may be influenced by past decisions. It compares existing methods, not a new breakthrough.
