Primary Outcome Measures:
  • Acute toxicity [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
    Assess acute toxicity and wound healing complications from the preoperative radiation treatment as per NCI CTCAE Common Toxicity Scale.

Secondary Outcome Measures:
  • Chronic toxicity [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Assess late-onset toxicity associated with a single fraction radiation treatement as per RTOG/EORTC Late Radiation Toxicity Scale

  • Cosmetic outcome [ Time Frame: 5 years ] [ Designated as safety issue: No ]
    Cosmesis will be evaluated as per the EORTC Breast Cancer Cosmetic Rating scale.

Other Outcome Measures:
  • Ipsilateral breast cancer recurrence [ Time Frame: 5 years ] [ Designated as safety issue: Yes ]
