First seen Jan 06, 2026 · Last updated May 16, 2026 · Updated 21 times

Summary

This study tests if a special green dye called indocyanine green (ICG) can find cancer in lymph nodes as accurately as the standard two-dye method in people with breast cancer who have already had chemotherapy. About 100 adults will receive both the new dye and the standard dyes during surgery to compare how many cancer-containing nodes each method finds. The goal is to see if the simpler ICG method can replace the standard approach, reducing side effects and improving patient experience.
