A mass localization device includes a catheter and a needle. In one embodiment, the catheter includes inner and outer walls spaced from each other and creating a gap between the walls extending along substantially the entire length of the catheter. The distal portion of the outer wall includes an inflatable balloon. In use, the balloon is positioned proximate the mass and inflated to make the mass palpable. An incision to the mass can be achieved by the shortest possible distance since the mass is made palpable.
