Which clock times are the same in each breast?

In mammography, the clock face analogy is often used to describe the location of findings within the breast. When considering the clock times relative to each breast, each time represents a specific area on the breast, much like how hours are positioned on a traditional clock.

When we refer to the times of 3 and 9, both positions are located on the outer sides of the breast. This means that the area at 3 o'clock on the right breast corresponds directly with the area at 9 o'clock on the left breast, making these two positions mirror images of each other. This symmetry allows for a standard way to discuss breast anatomy and any potential lesions or masses that may develop within these regions.

Other clock times mentioned represent different areas: for instance, 10 and 2 would correspond to the upper outer and upper inner quadrants, 5 and 7 to the lower outer and lower inner quadrants, and 12 and 6 to the upper and lower poles. None of these pairs share the same anatomical relationship across both breasts, which is why the option referencing 3 and 9 stands out as the correct answer.
