Description
Chiu and colleagues published a 2026 trial on a magnetic tracer for breast cancer surgery. Surgeons check the first lymph node, the sentinel node, to stage early breast cancer. The standard method pairs a radioactive tracer with a blue dye. The trial tested iron oxide particles that a magnet probe can find instead.
Nearly 300 patients were split between the magnetic tracer and the standard pair. The magnetic method found the sentinel node in over 99 percent of cases. The standard pair scored a perfect rate, a gap within the set limit. One failure occurred in the magnetic group across 153 procedures. The authors back the magnetic tracer as a sound stand-in option. The trial ran from 2021 to 2024 across several hospital centers.
