Breast UltrasoundDiagnostic Mammography | Breast Biopsy | Breast Ultrasound | Ductogram | Other Diagnostics Procedures Breast ultrasound is useful for the evaluation of some breast masses and is the only procedure that can determine if a cyst is present, without performing a needle biopsy. It is not routinely used for breast cancer screening, because calcifications or some small masses cannot be seen on an ultrasound. Ultrasound is used in biopsies to locate the areas of breast abnormality that cannot be felt by the physician. |
