The device is a cylindrical tubular member having an open circular end which is the marking element and having a pair of cross markings at the other end on an optically transparent wall to permit optical centering of the device with respect to the breast areola prior to skin marking. A preferred embodiment includes a pair of markers in a common cylindrical tubular member having one circular diameter at one end and a different circular diameter at the other end.
