1. A CT-scan showing the recent "Lumpectomy" site (highlighted) where the Mammosite Catheter will be implanted.
2. The Mammosite Catheter is then surgically implanted in the previously mentioned "Lumpectomy" site through a small incision on the side of the breast.
3. The balloon on the catheter will be filled or “inflated” to a minimum of 35cc (diameter of 4cm) or a maximum of 70cc (diameter of 5 cc). The bulb is filled with dilute x-ray contrast (3%) and saline. The lumpectomy site is closed leaving the catheter handle exiting the breast at a separate site. Post-operatively; the patients will go to The Cancer Center of Irvine, Radiation Therapy Department where, under the direction of Dr Kenneth Tokita, the radiation is delivered. In general this appointment will be the day after surgery, or the first working day, if the surgery was done on a Friday. (see Brachytherapy for more info)
