What is a Breast Ultrasound?
A breast ultrasound is used in conjunction with a mammogram to help investigate a specific area of the breast where a problem is suspected. This procedure is commonly performed to determine if an abnormality or a palpable lump is a fluid-filled cyst or a solid tumor (benign or malignant). It may also be used to identify masses in women whose breast tissue is too dense to be measured accurately by mammography. If a breast lump or breast abnormality has been detected, our radiologist will consult with your doctor, who may want to order a biopsy.
Ultrasound is generally not performed as a screening procedure, as many more abnormalities that may require biopsy are seen than are seen with mammography. These abnormalities usually are not cancer (false positives), and this limits its usefulness.
