NCT ID NCT07010939
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 2 times
Summary
This study follows 3,000 women with early-stage breast cancer to understand how local treatments like surgery and radiation affect their quality of life and cause side effects. Participants will complete surveys and undergo heart, lung, and blood tests over time. The goal is to find patterns and risk factors that could help future patients recover better.
