Breast volume measurement of 598 women using biostereometric analysis

A study of the volumes of the right and left breasts of 598 subjects was undertaken using biostereometric analysis. This measurement uses close-range stereophotogrammetry to characterize the shape of the breast, and is noncontact, noninvasive, accurate, and rapid with respect to the subject involvement time. Using chi-square tests, volumes and volumetric differences between breast pairs were compared with handedness, perception of breast size by each subject, age, and menstrual status. No significant relationship was found between the handedness, age, or menstrual status of the subject and the breast volume. Several groups of subjects were accurate in their perception of breast size difference. Analysis did confirm the generally accepted clinical impression of left-breast volume dominance. These results are shown to be consistent with those of a previous study using 248 women.
