IntraOperative Radiation Therapy (IORT)

If you receive an early-stage breast cancer diagnosis and would like to conserve your breast, electron-based intraoperative radiation therapy (IORT) is a proven option for you.

Innovative Breast Cancer Treatment Close to Home

As one of only eight cancer centers in the United States to offer IORT, Avera’s expert radiation oncologists and breast cancer surgeons provide this leading-edge treatment at Avera Cancer Institute Sioux Falls.

IORT targets the tumor with a high dose of radiation during lumpectomy surgery.

After removing the tumor and some of the surrounding breast tissue, a radiation oncologist will direct radiation to the area where the tumor was located.

Benefit from Advanced Treatment

The precision and strength of IORT treatment reduces the need for additional radiation therapy after surgery. In fact, if you’re 60 years old or older, you may only need the one radiation boost at the time of surgery. You’ll save time by not having to drive to and from daily sessions and experience benefits, such as:

  • Immediate results – With IORT, a high dose of electron-based radiation is delivered in minutes during surgery. This immediate treatment of tumor site helps kill cancer cells before they can spread.
  • Fewer treatments – Typically, a lumpectomy is accompanied by six to seven weeks of daily radiation treatments after surgery. However, a lumpectomy paired with IORT can shorten the treatment cycle to only three weeks. In some cases, one IORT treatment is all that’s needed. This means you can start feeling like yourself again sooner.
  • Fewer side effects – Direct treatment to the tumor site means less damage to healthy tissue. European trials using IORT in early stage breast cancer patients indicate a reduction in skin toxicity.

Experience the Difference

Learn more about IORT and be encouraged by stories from women who have already experienced the benefits of IORT treatment.

"Within less than a year after my surgery, it would have taken an experienced person a close examination to know that I had breast surgery at all. I was just so amazed that this could be done in a way that every time I look in the mirror I didn’t have to think about the surgery. I’m so thankful that I was able to participate and that Dr. Julie Reiland was able to do that for me. It was a far different experience than I expected and a far different outcome than I expected to have."
