In mammography, what does a "diagnostic" mammogram primarily assess?

A "diagnostic" mammogram primarily assesses suspicious changes in breast tissue. This type of mammogram is specifically designed to evaluate abnormalities that have been detected in a screening mammogram or clinical examination. It aims to provide a more detailed examination of the breast tissue and can involve additional views or imaging techniques to clarify the nature of any irregularities.

The focus of a diagnostic mammogram is to determine whether a suspicious area is benign or malignant, thereby helping healthcare providers formulate a treatment plan if necessary. This makes it a critical tool in the early detection and intervention of breast cancer and other breast-related issues.

The other options describe different aspects of breast health but do not accurately represent the purpose of a diagnostic mammogram. Routine breast checks and screenings primarily focus on identifying potential issues in asymptomatic women, while assessments of breast density are often more general and not diagnostic in nature.
