An improved method for marking a breast cyst or a breast biopsy site, using the steps of: inserting a first needle into the breast cyst or the breast biopsy site; removing fluid from the breast cyst or tissue from the breast biopsy site; inserting a second needle into the cyst or the breast biopsy site that includes a clip; pushing an actuator and a driver of the second needle along an inside portion of the second needle so that the clip travels down the inside portion of the second needle; and expelling the clip along a ramp that is in alignment with a hole in the first needle and the second needle resulting in the insertion of the clip into the breast cyst or the breast biopsy site to mark the same.
