Eligibility Criteria

Male or female participants at least 40 years old.

Inclusion Criteria: - Be a Tis, T1, N0, M0 AJC Classification - Have negative surgical margins (> or = 2 mm) after final surgery - Should have adequate skin spacing between balloon surface and surface the skin (> 7 mm)* - Patients with infiltrating lobular histologies should have breast MRI scanning as part of the initial staging to verify localized T1, or Tis disease - Multifocal findings (define as 2 or more breast quadrants) on MRI scanning should be further evaluated by ultrasound and, if necessary biopsy, to exclude multiquadrant disease. Exclusion Criteria: - Be pregnant or breast-feeding - Have collagen-vascular disease - Inadequate surgical margins (< 2 mm) - Patients with malignant/suspicious calcifications
