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.

What this could lead to
If successful, this study could help doctors better predict and manage treatment side effects, improving quality of life for breast cancer survivors.
What could go wrong
This is an observational study, not a treatment trial. It will not directly change or improve care during the study period.
