Is your patient a candidate for Intrabeam?

Intrabeam technology (also referred to as intraoperative radiation therapy, or IORT) is a single-dose radiation treatment delivered in the operating room immediately following a partial mastectomy/lumpectomy. An ideal candidate for Intrabeam is typically:

  • A woman 50 and over
  • Whose tumor is three centimeters in size (just over an inch) or smaller
  • Non-lobular and both estrogen- and progesterone-positive
