If a lesion is described as Location 2 in the 123 method, where is it located relative to the nipple?

• A. Near the nipple
• B. Mid distance from the nipple
• C. Periphery of the breast
• D. Near the chest wall

Answer: (B)

The 123 method maps a lesion along the line from the nipple to the chest wall using three equal zones. Location 1 is the zone closest to the nipple, location 2 is the middle zone, and location 3 is nearest the chest wall. So a lesion described as Location 2 sits at mid distance from the nipple—roughly halfway along that line. It’s not right at the nipple, and it’s not at the outer edge near the chest wall. This standardized labeling helps different clinicians communicate the exact spot across imaging and planning.
