Ultrasonography
(ultrasound): An imaging
method that uses high-frequency waves to image the breast or other parts of the body.
High-frequency sound waves are transmitted from a transducer through the area of the body
being studied. The sound wave echoes are picked up and displayed on a computer monitor or
television screen. Ultrasound is a painless method that is sometimes useful in
distinguishing fluid-filled cysts from solid tumors. Ultrasound involves no exposure to
radiation.
Unifocal: Term used to describe cancer that is
present in only one spot in the breast.
Unilateral: Affecting one side of the body. For
example, unilateral breast cancer occurs in only one breast. (See also bilateral).
Unproven methods of cancer management:
