title: Mammographic needle localisation of impalpable breast lesions.
abstract: Refinements in mammography have led to an increased number of needle localised breast biopsies for impalpable breast lesions. This paper review 139 needle guided biopsies from June 1986 to December 1990 in 132 patients. Forty four patients (32%) biopsied had malignant lesions the vast majority (91%) of which were reported as either non-invasive or invasive less than 2 cm in diameter. Fourteen patients in this group had ductal carcinoma in-situ. When compared with 100 consecutive palpable breast carcinomas during the same period, needle localised biopsies had a higher proportion of non-invasive lesions and fewer were associated with lymph node involvement. Needle guided breast biopsy detects carcinoma at an earlier stage and may reduce morbidity and mortality from breast cancer.
