First seen Jun 27, 2026 · Last updated Sep 01, 2026 · Updated 2 times
Summary
This study tests whether giving 6 months of hormone therapy before surgery helps remove all cancer cells in women with early-stage, estrogen-positive breast cancer. It involves 8 postmenopausal women with low-risk, node-negative tumors. The goal is to see if this approach leads to cleaner surgical margins, reducing the need for additional treatment.
