Non-mass Lesions on Breast Ultrasound Images



Breast lesions are classified into two categories: mass and non-mass abnormalities in ultrasound images [1, 2, 3]. A mass means a lump with components differing from the surrounding tissue; on the other hand, a non-mass abnormality means a lesion that is difficult to recognize as a mass on ultrasound images (Fig. 12.1).
