Cryoablation as a Minimally Invasive Alternative to Surgery for Managing Ductal Carcinoma In Situ

The cryoprobe tip will be inserted into the breast and directed under ultrasound guidance to the location where the ultrasound visible marker is located. Next, the cryoprobe will be used to freeze a 4 X 3 X 3 cm diameter area of DCIS using two separate 10-minute freeze cycles separated by a single 10-minute thaw cycle. The cryoprobe will remain in place the entire time. After the second freeze, the cryoprobe will be withdrawn from the breast and a bandage will be applied to the skin.
