Could a Two-Week radiation blast be enough for early breast cancer?

NCT ID NCT01203839

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests a shorter radiation treatment (partial breast irradiation) for women with early-stage breast cancer or a pre-cancer called DCIS. Instead of treating the whole breast for 5-7 weeks, radiation is given only to the area where the tumor was removed, for just 2 weeks. The goal is to see if this approach is safe, has fewer side effects, and keeps the cancer from coming back in the same breast.
