Radiofrequency-Guided Localization in Patients With Abnormal Breast Tissue Undergoing Lumpectomy

Trial ID or NCT#



not recruiting iconNOT RECRUITING


This pilot clinical trial studies the use of the radiofrequency-guided localization in patients with abnormal breast tissue undergoing lumpectomy (a type of breast-sparing surgery). The radiofrequency identification localization system consists of an implantable radiofrequency identification tag and a hand-held radiofrequency reader to mark abnormal breast tissue before surgery and later surgically retrieve them. Radiofrequency-guided localization may make it easier to find and remove abnormal breast tissue during lumpectomy.
