 Breast density can make breast cancer difficult for a radiologist to see on a mammogram. Also, research has shown that women who have dense breast tissue are more likely to develop breast cancer in their lifetime than women who do not have dense breast tissue. Automated Breast Ultrasound ABUS is a breast imaging technology which is less affected by a womans breast density, and is currently FDA approved for use by doctors and sonographers as an adjunct to mammography. ABUS is most commonly used in the diagnostic setting, when a woman has a known breast abnormality or symptom.
