Breast Ultrasound
What is Breast Ultrasound?
A Breast Ultrasound is a procedure that uses sound waves to create an image of the tissues inside your breast. Used in conjunction with a Mammogram, a Breast Ultrasound identifies the composition of a lump in the breast to determine whether it is a cyst (fluid filled) or a solid mass. Mammography alone cannot differentiate between a cystic mass and a solid mass. That is why physicians often recommend a Breast Ultrasound as a follow-up to a Mammogram when a mass is discovered.
