Where is a lesion located in the 10 O'clock position?

A lesion located in the 10 O'clock position corresponds to the upper-outer quadrant of the breast. The breast is often divided into quadrants using a clock face orientation, where the nipple is at the center. In this system, the 12 O'clock position is at the top, the 3 O'clock position is to the right, the 6 O'clock position is at the bottom, and the 9 O'clock position is to the left.

At the 10 O'clock position, which lies slightly to the left and above the nipple, the lesion is situated in the upper-outer quadrant of the breast. This understanding is crucial for accurately locating lesions during mammography and for communicating findings effectively among healthcare professionals. It assists in identifying the specific area of concern during imaging assessment and when planning any further investigation or treatment.
