Thirty patients presenting through the Breast Screening Programme with
impalpable breast abnormalities clearly visible on ultrasound, underw
ent non-invasive ultrasound localization. The patient was scanned so t
hat the ultrasound abnormality lay below the probe and the skin at thi
s site marked with a skin marker. In all cases the abnormality was eas
ily identified and removed at surgery. All the surgical biopsies conta
ined either a carcinoma (17 cases) or fibroadenoma (13 cases). This no
n-invasive technique is a simple and accurate method for localizing sm
all ultrasonically visible breast abnormalities.
