PRIMARY OBJECTIVES:
I. To evaluate the procedural success rate of using the Visualase magnetic resonance (MR)-guided laser system to target, access, thermally monitor, and focally ablate MR-visible breast cancer lesions.
2\. To obtain preliminary data on ablative success using pathologic assessment for specimen excised subsequent to the ablation.
OUTLINE:
Patients undergo MR-thermal image guided laser interstitial thermal therapy (LITT) over 1 hour.
After completion of study treatment, patients are followed up at 3-7 days.
