ABSTRACT
Brachytherapy (brak-e-THER-uh-pee) is a procedure that involves placing radioactive material inside your body. Brachytherapy is a type of radiation therapy that's used to treat cancer. Brachytherapy is sometimes also called internal radiation therapy. In this type of radiation therapy, the radioactive source delivered through seeds, ribbons, catheters or wires is placed within or just next to a tumor and may be left in place permanently or temporarily, depending on the cancer type and location. That allows eliminations of cancer cells from inside the tumor mass as opposed to a radiation beam going through healthy tissue to reach tumor cells (in case of external beam radiotherapy).
