The FDA rule mandating women be notified of their breast density is the result of intense lobbying by women who found champions in state and federal legislators to get laws introduced and passed.
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound.

It is also used for ultrasound-guided aspiration of breast abscess, [4] of breast cysts, and of seromas. [5]
With automated whole-breast ultrasound, the ultrasound transducer is guided over the breast in an automatic manner. The position and speed of the transducer is regulated automatically, whereas the angle of incidence and the amount of pressure applied is set by the human operator.
