Magnetic vs. wire: which tumor marker is better for breast surgery?
NCT ID NCT06906601
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two methods for marking non-palpable breast tumors before surgery: magnetic clips and traditional metal wires. Researchers will track costs, how well the marker finds the tumor, and patient satisfaction in 772 women across France. The goal is to see if magnetic clips offer a better or cheaper option for breast-conserving surgery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
magnetic clip localization
What this could lead to
If magnetic clips prove cheaper or better, they could replace wires for marking tumors before breast surgery, improving patient experience and reducing costs.
What could go wrong
This is an observational study, not a randomized trial, so results may be biased. It only looks at costs and short-term outcomes, not long-term cancer control.
