Management of radial scars found at percutaneous breast biopsy.

Objective: To determine whether percutaneous biopsy can safely differentiate radial scars (RS) that can be followed from those that require excision.

Methods: Retrospective analysis of prospectively collected data regarding 15 986 biopsies was performed at the Centre Hospitalier de l'Université de Montreal between October 1995 and December 2003 and yielded 227 RS. The type of biopsy, number of cores, and mammographic characteristics were recorded.
