Lumpectomy Specimen Margin Evaluation With Tomography and Structured Light Imaging

The purpose of this study is to test a new surgical imaging system called "Structured Light Imaging (SLI)." This system is designed to examine tissue removed during breast cancer surgery to see whether the tissue's edges contain cancer. The current standard of practice is to remove the breast tumor tissue and send the tissue to the lab for analysis following surgery. One in five women (in the US) must later return for a second surgery to remove cancer cells that the lab found remaining in the tissue. In this study, researchers hope that the new SLI system may detect the cancer cells in the tissue's edges by imaging at the time of surgery. If successful, in the future we may use this system to improve entire cancer removal at the time of surgery, and reduce the need to perform a second surgery to remove additional breast tissue.
