Randomized comparison of sitting and prone positions for stereotactic fine-needle aspiration breast biopsy.

In a prospective randomized study, 103 women had stereotactic biopsies performed either in the prone (n = 51) or sitting (n = 52) position. Questionnaires were administered before and after biopsy, to measure anxiety, pain and subjective experience in all patients. Vasovagal reactions were scored from 0 to 2 according to severity. There was no significant difference between biopsies performed in the sitting or the prone position with regard to overall tolerance. Significantly more patients biopsied in the prone position (15 of 51, 29 per cent) than in the sitting position (seven of 52, 13 per cent) would prefer premedication before a repeat biopsy (P = 0.04). Of the total patient group, three women fainted, one in the prone position and two others in the sitting position. Breast biopsies performed in the prone or sitting position are equally well tolerated. Somatic reactions such as fainting are not a major problem during breast biopsy; however, attention should be focused on patient care, including information given before the procedure.
