First seen Nov 01, 2025 · Last updated May 21, 2026 · Updated 26 times

Summary

This study looks at why some hormone-positive breast cancers become resistant to anti-estrogen treatment. About 100 women with early-stage breast cancer will receive standard hormone therapy for 4-12 weeks before surgery. Researchers will analyze tumor samples to find changes in certain proteins that may predict resistance, helping to personalize future treatments.
