If a breast lesion is visible in only one mammographic view, what does this allow?

• A. You can accurately locate the lesion within the breast
• B. You can narrow the location to half of the breast
• C. You can determine malignant potential
• D. You can locate the lesion in the opposite breast

Answer: (B)

When a lesion shows up in only one mammographic projection, you can’t pin down its exact three‑dimensional position, but the image geometry still lets you narrow its location to one half of the breast. Two standard views sample different angles, so if a lesion is visible in a single view, its true position must lie within the half of the breast that corresponds to that view. This focused localization is helpful for guiding ultrasound correlation or targeted biopsy.

This finding doesn’t tell you about malignant potential and it doesn’t allow locating the lesion in the opposite breast or determining exact depth from a single view.
