Wires or RFID Tags in Breast Cancer Excision?

Use of radiofrequency identification (RFID) to tag breast cancers for surgical excision had similar success as the standard of using wires to mark lesion locations prior to surgery, researchers reported here from a small retrospective study. "We found no statistically significant differences in percentage of cases with positive margins, in close margins, and in the need for re-excision in comparing the two modes of marking the breast cancers," said Stephanie Riviere, MD, a resident in pathology at Rhode Island Hospital/Warren Albert Medical School of Brown University in Providence, Rhode Island.
