OBJECTIVES:
Primary:
To determine the toxicity with adjuvant hypofractionated whole breast radiation with simultaneous tumor bed boost (SIB) in women with early breast cancer after breast conserving surgery.
Secondary:
To determine the short term cosmetic and quality of life of the participants treated with this regimen.
To determine the local control of the participants treated with this regimen.
