Brief Summary:
The purpose of this study is to show that addition of device use to a routine breast cancer tumor excision procedure is beneficial and assists the surgeon in correctly determining the extent of excision.

Condition or disease Intervention/treatment Phase
Breast Cancer Device: MarginProbe Procedure: Lumpectomy Not Applicable

Detailed Description:
The study is a prospective, multi-center, randomized, double arm study demonstrating the effectiveness of the device in adjunctive use for locating the tissue for additional excision following primary specimen excision. One arm is a "Standard of Care" (SOC) Control group and the other arm a "Device+SOC" group.In the "Device +SOC" group the surgeon will use the MarginProbe device on the tissue specimen removed during the surgical procedure.The surgeon will use the results derived from the device and other routine assessments to decide if it is necessary to remove some additional breast tissue.

Arm Intervention/treatment
Active Comparator: SOC
Standard of Care arm - standard of care lumpectomy procedure
Procedure: Lumpectomy
Standard of care lumpectomy procedure

Experimental: Device + SOC
Use of the device in addition to the standard of care lumpectomy procedure.
Device: MarginProbe
Device use to assess margin status of the excised specimen surface.

Procedure: Lumpectomy
Standard of care lumpectomy procedure

Primary Outcome Measures :
  1. The Primary Effectiveness Endpoint is a Measure of Intraoperative Success in Addressing Positive Margins as Detected by Permanent Pathology)by Additional Oriented Tissue Re-excision From the Surgical Cavity. [ Time Frame: two weeks after surgery ]
    Tests the efficacy of the device to intra-operatively assess positive margins (superiority) - CSR is 'positive' when all positive margins, as detected by histology, on the main specimen addressed intra-operatively
