IntraOperative Electron Radiation Therapy

Leading the way in breast cancer

Is this treatment for you?

IOeRT is an option for people diagnosed with early stage breast cancer. It can be an alternative to a mastectomy, which is removal of the total breast.

IntraOperative Electron Radiation Therapy is the first of its kind in the region. This innovative treatment allows your radiation oncologist to directly treat the site of your tumor — the area that is at highest risk for cancer to reoccur.

How does it work?

IOeRT is done at the same time as a lumpectomy, a procedure that removes the tumor and some of the surrounding breast tissue. The radiation oncologist then directs five times the normal radiation dose directly to the area where the tumor used to be. Doing this treatment during surgery provides a visual of the tumor site and allows more precise treatment.

What are the benefits?

This treatment is more precise and can also decrease radiation treatment after surgery, saving time and money on travel to and from daily sessions.

  • Immediate Results
    With IOeRT, 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
    A lumpectomy typically is accompanied by six to seven weeks of daily radiation treatments after surgery. A lumpectomy paired with IOeRT can shorten the treatment cycle following surgery by 50 percent so 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 IOeRT in early stage breast cancer patients indicate a reduction in skin toxicity.
