A device and method for performing a biopsy on a human breast. The inventive device and method includes a K-wire positionable through a lesion to be removed. A widening incision is made in the breast and permits concentric positioning of a cylindrical cannula to a point above the lesion. The cannula is advanced into the breast about the lesion to cut a cylindrical incision therearound. A snare wire is concentrically positioned over the cannula and tensioned to effect severing of a cylindrical volume of tissue within the cannula for removal from the breast.
