NCT ID NCT01766297
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests proton radiation therapy for women with early-stage breast cancer. The goal is to see if targeting only the tumor area can keep cancer from coming back while causing fewer side effects. About 132 women aged 50 and older will take part. Researchers will track recurrence, side effects, and quality of life over time.

Proton radiation therapy
What this could lead to
If successful, this could offer a more precise radiation option for early breast cancer, potentially reducing side effects and improving quality of life.
What could go wrong
This is a mid-stage trial with a small number of participants. It may not show better outcomes than standard radiation, and long-term side effects are still being studied.
