How is APBI performed?
Breast brachytherapy involves placing flexible plastic tubes called catheters or a balloon into the breast. During treatment, the catheters or the balloon are connected to a machine which sends out a small radioactive seed directly into the catheter which is placed where the tumor was removed. The radiation is left in place for several minutes, twice a day. After the end of the five days, the catheters or balloon are removed.
