NCT ID NCT03797482

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study looks at how oxygen levels in breast tumors change during surgery and how those changes affect gene activity. Researchers will take small tumor samples at three points during surgery from 500 women with breast cancer. The goal is to understand the body's response to surgery, not to test a new treatment.
