Biopsy vs. surgery: could some breast cancer patients avoid the knife?

NCT ID NCT02455791

First seen Oct 01, 2025 · Last updated Jun 14, 2026 · Updated 33 times

Summary

This study tests whether a less invasive ultrasound-guided biopsy can accurately tell if breast cancer has been completely wiped out by chemotherapy, compared to standard surgery. Researchers will enroll 43 adults with triple-negative or HER2-positive breast cancer who have finished pre-surgery chemo. If the biopsy proves reliable, some patients might be able to skip surgery in the future.
