Intervention Details:
  • Procedure: ADRC-Enhanced Autologous Fat Transplant
    Autologous fat harvested from the patient is enhanced with ADRCs derived from a portion of the harvested fat and transplanted into the breast(s) that have a volume deficit post lumpectomy. This is a single arm study with no control. All patients receive cell therapy.

Primary Outcome Measures :
  1. Patient and physician satisfaction with functional and cosmetic results. Improvement in overall breast deformity measured at 12 months compared to baseline. [ Time Frame: 12 months ]

Secondary Outcome Measures :
  1. Change in breast volume and shape at 6 and 12 Months compared to baseline. Improvement in skin pigmentation abnormalities at 6 and 12 months compared to Baseline. Improvement in overall breast deformity at 6 Months compared to Baseline. [ Time Frame: 6 months and 12 months ]
