NCT ID NCT03878342

First seen Jan 31, 2026 · Last updated May 07, 2026 · Updated 14 times

Summary

This study looks at whether women aged 50 and older with a very low-risk type of early breast cancer (called DCIS) can avoid radiation therapy after lumpectomy. The goal is to see if the cancer stays away without radiation, reducing unnecessary treatment and side effects. About 295 participants are being followed for 5 years to check for any return of cancer in the breast.
