DIAGNOSIS AND BIOPSY OF NONPALPABLE BREAS T-LESIONS

In a retrospective analysis we reviewed 117 needle-localized biopsies of nonpalpable breast lesions in 115 women from the senologic out-pati ent clinic at the Women's Hospital of the University of Berne. In a lo gistic regression analysis, the age of the patient, the presence of gr ouped and irregular microcalcifications as well as the presence of a s tellate lesion in mammography correlated closely with the diagnosis of breast cancer. The prevalence of malignant lesions, which was equal t o the rate of preoperative correctly diagnosed malignancy in this grou p, was 22.2%.
