Follow-up imaging, biopsy, or surgery must have a reproducible system of lesion localization. At the least, one must include the side (right or left breast), the clock face with the center at the nipple, the distance from the nipple or the zone (typically, the breast is divided into 5 zones comprising the subareolar zone [SA], 3 circular concentric zones outside the SA, and the axillary zone [AX]). The probe orientation is also mentioned, which could be horizontal, vertical, radial, or antiradial (at right angle to the radial section at that point). Additional oblique sections are often required to assess the longest diameter and the short axis of lesions. Including the depth of the lesion from the skin may be helpful, but this is not always necessary.

All lesions should be recorded in at least the long axis and short axis, appropriately labeled with the annotation information.
