title: Stereotactic breast biopsy as an alternative to open excisional biopsy.
abstract: BACKGROUND
  Health care cost continues to play a dominant role in our society. Technological advances are expensive, with the possible exception of stereotactic breast biopsy. We must learn other alternatives that give the same diagnostic accuracy at lower cost. The intention of this study was to find other acceptable alternatives to open excisional breast biopsies.
  
  
  METHODS
  Patients were referred to Baylor University Medical Center between May 1990 and June 1992 for stereotactic breast biopsy of nonpalpable mammographic abnormalities. Before stereotactic biopsy, lesions were categorized into low or high suspicion for malignancy based on screening mammography. Slides were reviewed by a pathologist and the histological diagnosis was compared with mammographic characterization. Benign histology confirming the low-suspicion mammographic abnormality demonstrated mammographic and histologic correlation. Mammographic follow-up was recommended.
  
  
  RESULTS
  Two hundred twenty-five women underwent 250 stereotactic breast biopsies. Malignancy was diagnosed in 47 patients; the remaining 203 lesions were benign on pathological examination and are being followed regularly. Seventy-eight percent of the lesions were characterized as low suspicion for malignancy, and 22% were characterized as high suspicion. The average cost savings per lesion using stereotactic biopsy was $1,629.
  
  
  CONCLUSIONS
  Stereotactic breast biopsy is an acceptable, less expensive alternative to open excisional biopsy for diagnosing nonpalpable mammographic findings.
