This research study is designed to look at whether the routine use of shave margins (by taking extra tissue at the time of partial mastectomy surgery) will reduce the chances of having positive surgical margins requiring another surgical procedure, and whether this affects the long-term chances of getting cancer back in your breast.

Procedure: No Shave Margins

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study

Primary Outcome Measures:
  • Optimal surgical treatment [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    To determine whether routine shave margins in breast cancer patients undergoing partial mastectomy will result in more optimal surgical treatment of breast cancer patients, as defined by reduced positive margin rates

Secondary Outcome Measures:
  • Cosmesis [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    To determine the effect of routine shave margins on cosmesis

  • Operative time [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    To determine the effect of routine shave margins on the time in the operating suite.

  • Volume of tissue resected [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    To determine the effect of routine shave margins on the volume of tissue resected.
