Brief Summary
The purpose of the project is to compare Radiofrequency identification device (RFID) localization technique with the current clinical standard wire localization technique. The Investigator's hypotheses is that the RFID localization technique is non-inferior to wire localization for breast lesions (tumors). The study will be conducted in two parts. The purpose of Part A is for physician training with the RFID device. Nine subjects will undergo RFID and wire localization prior to breast lesion excision. This will allow the breast radiologists and surgeons to become comfortable with RFID device placement and retrieval. Additionally, the investigators will pilot the data collection surveys and chart review methodology to be used in Part B. The purpose of Part B is to conduct a randomized clinical trial to assess whether RFID localization is non-inferior to wire localization for breast lesions. For this part, sixty subjects will be randomized to RFID (N=30) or wire localization (N=30) at time of enrollment. Surveys will be used to gather data from participants, radiologists, surgeons, and technologists/mammography nurses. A variety of data will be collected including, but not limited to, information on tumor size, location, depth; subject demographics; adequacy of tumor margins, re-excision rates, accuracy of wire or chip placement, and surgical complications.

RFID and Wire Localization
OTHERPart A of this project is for physician training to master the technique of RFID placement and retrieval. On the day of surgery prior to going to the operating room, all participants will have the RFID placed first to allow radiologists to become familiar with placement of the RFID localizer. Participants will then immediately undergo wire localization. Either ultrasound or mammogram guidance will be used for the localization at the discretion of the performing radiologist. Surgeons will use a reader to locate the RFID chip during surgery. The wire will be present in the event the area of concern cannot be adequately located with the reader.
RFID Localization
EXPERIMENTALParticipants will be stratified based on technique of localization (either US guidance or mammographic guidance). They will then be randomized to receive either the wire or RFID localization. There will be four visits: one pre-op breast surgery visit in which enrollment will occur, one radiology procedure visit for localization, one surgical visit, and one post-operative visit. This is the same number of visits as standard of care.

Interventions
The RFID and wire localization devices used in this study are FDA approved for the image guided localization of breast tumors prior to surgical excision. The two techniques for localization will be compared in this trial.

Both RFID and the standard of care wire localization will be performed for physician training.
