Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patients with Stage 0 ductal carcinoma in situ (Tis (DCIS), Stage T1-T2, lymph node negative(N0) breast cancers will be randomized to receive whole breast radiotherapy with a concomitant boost to the tumor bed over 15 fractions (Arm 1, standard) versus 10 fractions (Arm 2, experimental).
