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.
