Mammography
Large well circumscribed mass in the right outer breast centrally. There is a complete low density halo which encircles the mass on both views. Note also that despite its large size it is not very dense. The density is similar to that of the surrounding fibroglandular tissue and the normal parenchymal elements are discernible through the mass. These are reassuring morphologic features.
Nonetheless, as it is a solitary mass, in the absence of prior imaging showing stability, it warrants further workup with ultrasound.
