The value of 6-month interval imaging after benign radiologic-pathologic concordant minimally invasive breast biopsy.

Background: Current National Comprehensive Cancer Network guidelines recommend repeat imaging 6-12 months after a benign radiologic-pathologic concordant image-guided breast biopsy. We hypothesized that interval imaging <12 months after benign concordant biopsy has a low cancer yield and increases health care costs.

Methods: An institutional review board-approved retrospective chart review identified 689 patients who underwent image-guided breast biopsy at Bryn Mawr Hospital between January and December 2010.
