Percutaneous Removal and Margin Ablation for Breast Cancer
Percutaneous Removal and Margin Ablation for Breast Cancer
We hypothesize that radiofrequency ablation after single-insertion image guided vacuum
 assisted biopsy (IVEB) can be used to achieve negative margins in small unicentric breast
 cancers (≤1.5 cm).
Using the Mammotome Breast Biopsy System (IVEB) in conjunction with MRI to predict extent of
 disease, ultrasound to direct removal of the tumor, touch preparation cytology for diagnosis,
 and ablation of margins using radiofrequency ablation (RFA), we propose to develop a
 comprehensive system for same-day diagnosis and treatment of patients with small breast
 lesions.
