Magnification in mammography can be used to assess what aspect of a lesion?

Magnification in mammography serves a crucial role in evaluating the margins of a lesion. When images are magnified, the radiologist can obtain a clearer and more detailed view of the edges of a lesion, which is essential for determining if the margins are smooth, irregular, or spiculated. The appearance of these margins can provide valuable diagnostic information regarding the nature of the lesion, such as whether it is benign or malignant.

In particular, irregular or spiculated margins may raise suspicion for malignancy, while well-defined margins are often associated with benign conditions. By focusing on the margins, magnification enhances the ability to identify subtle characteristics that would otherwise be obscured in standard imaging, allowing for more accurate assessments and treatment planning.

The focus on color, size, or composition in mammography is less relevant with respect to the magnification's primary function, as these factors can often be assessed independently of magnification techniques.
