Ultrasound-Guided Breast Cancer Cryoablation.

Percutaneous ultrasound-guided breast cryoablation is a minimally invasive technique that kills targeted tissue with extreme cold, requires only local anesthesia, and takes less than 45 minutes to complete. We discuss the indications for breast cryoablation, the mechanism of cell death, and types of commercially available devices; illustrate procedural technique; and review expected follow-up imaging findings in treated primary breast cancer.
