A Pilot Multi-Institutional Study to Evaluate the Accuracy of a Breast Cancer Locator in Patients With Palpable Cancers

This locator will be constructed pre-operatively, sterilized and provided to the surgeon at the time of procedure. The outline of the breast cancer on the breast surface at the point where the cancer is closest to the skin is built into the locator, so that the surgeon can simply apply the locator to the patient's breast and trace the tumor outline on the skin.
