Learning objectives

To define a simple guide that can be used by the radiologist to easily recognize the malignant features of a lesion on mammography.

Background

Breast cancer is the most common cancer and also the primary cause of mortality due to cancer in females around the World. An early, accurate and precise diagnosis is needed both to reduce mortality and to carry out radical but less mutilating surgeries. There are several diagnostic imaging methods with which it is possible to study the breast: Mammography Tomosynthesis Ecography MRI The role of mammography is of primary importance in the study of the breast, both in screening investigations and in control of already...

Findings and procedure details

To achieve an early and accurate diagnosis the radiologist should pay attention to the following malignancy features on a mammogram: 1. MASS: Bi-RADS definition: Breast masses are three-dimensional space-occupying lesions ( Fig. 6 ) in the breasts and they must be seen on at least two different mammographic projections. Radiologists have to evaluate: •Diameters: •Shape: irregular it is suspicious; ( Fig. 7 ) •Margins: Microlobulated: suspicious finding. Indistinct (historically ill-defined): suspicious finding. Spiculated with radiating lines from the mass: very suspicious finding. •Density:high or equal:...

Conclusion

Through careful analysis of the mammographic report, it is possible to establish which lesions are highly suspect and therefore which ones deserve in-depth diagnostic analysis. In this way, it is possible to increase survival and quality of life with less mutilating but more radical interventions.
