First seen Oct 01, 2025 · Last updated May 10, 2026 · Updated 28 times

Summary

This study looks back at over 1,000 women who had breast-conserving surgery for early breast cancer that couldn't be felt. It compares four techniques used to locate the tumor during surgery: wire guidance, radioactive seed, magnetic seed, and carbon dye. The goal is to see which method most reliably leads to complete tumor removal with clear margins, reducing the need for repeat surgery.
