First seen Nov 01, 2025 · Last updated May 15, 2026 · Updated 24 times

Summary

This study looks at why some hormone receptor-positive breast cancers become resistant to standard hormone-blocking therapy. About 100 women with early-stage breast cancer will receive anti-estrogen treatment for 4-12 weeks before surgery. Researchers will analyze tumor samples to find molecular changes that predict resistance, with the goal of personalizing future treatments.
