The anti radial orientation is described as being perpendicular to what?

• A. The ducts
• B. The skin
• C. The chest wall
• D. The nipple

Answer: (A)

Understanding how lesions relate to the ductal system helps interpret their orientation. The ducts in the breast radiate outward from the nipple, like spokes on a wheel. An anti-radial orientation means the lesion runs across these ducts, i.e., perpendicular to their direction. This is different from a radial orientation, which would follow along the ducts. So, the anti-radial orientation is described as being perpendicular to the ducts. The skin, the chest wall, and the nipple itself aren’t the defining reference for this term; the key relationship is to the ductal pathways.
