Intraoperative Radiation Therapy

Dr. GieldaNew option for early-stage breast cancer

A breast cancer diagnosis can be stressful and emotional. However, if caught early, you may have the option of avoiding weeks of radiation treatment.

Lakeland physicians are now using the ZEISS INTRABEAM® intraoperative therapy system to deliver a  targeted single-dose of radiation to the site of the tumor, after a Lumpectomy. 

Traditional external high-beam radiation requires patients undergo daily radiation to the whole breast, for a five or six week period.

The new therapy, also known as IORT, minimizes radiation exposure to healthy tissue and organs. It has also proven less costly, with limited side effects. Results have been so promising, Lakeland was asked to participate in the international TARGIT-B trial focused on the treatment.

It is important you have the advice and support of your breast care team before making an informed decision. Talk to your physician to see if IORT is right for you.  

Mammograms are key to early detection. Lakeland offers three convenient locations to serve you. Click here to schedule your appointment.

IORT Frequently Asked Questions

How effective is INTRABEAM IORT?
In 1998, a group of international researchers began investigating this method of radiotherapy delivery for breast cancer. The primary study tested the effectiveness of an intraoperative dose of radiation delivered using the INTRABEAM System compared with up to six weeks of conventional external beam radiation treatment (EBRT) for early stage breast cancer. The results of the trial were first presented in 2010 and show the overall number of cancer recurrences for both the EBRT and IORT patients were very similar. Ask your physician about the significant results from the trial named TARGIT-A, including complications.

How is INTRABEAM radiotherapy administered?
INTRABEAM IORT is delivered during breast-conserving surgery in the operating room while the patient is still asleep. Radiation is typically delivered for 20 to 30 minutes The treatment is delivered inside the lumpectomy cavity which minimizes radiation exposure to healthy tissue and organs.

Is IORT right for me?
For many women, INTRABEAM IORT is a viable treatment option. The physicians coordinating your breast conservation therapy will determine whether INTRABEAM radiotherapy is an appropriate treatment for your type of cancer.

What if I have been prescribed whole-breast radiation?
Some women undergoing conventional radiation treatment may have the choice of receiving INTRABEAM radiotherapy as a boost dose during cancer surgery, before the start of external radiation. This initial boost dose of radiation can be used in conjunction with standard course of external breast radiation.

Didn’t Miss a Beat - Judi Greene

Physicians: Benjamin Gielda, MD


For Stevensville resident, Judi Greene, her 75th birthday is one she won’t ever forget. During her yearly mammogram, which she had religiously on her birthday each year, her radiologist suggested they perform a biopsy on a small spot detected in her left breast.

“It never dawned on me that it might be cancer – it didn’t run in my family and all my mammograms came back clear in the past,” said Judi.

However, a few days later Judi learned the six millimeter spot was in fact Stage I breast cancer. Although the news came as a shock, she didn’t worry for long after meeting oncology nurse navigator, Shelley Wilkinson, RN, CBCN, at the Marie Yeager Cancer Center. 

“The most important thing was having people around who understand what you’re going through and can explain what your options are,” said Judi. “Shelley really put me at ease and answered all my questions – it didn’t seem like I had anything to worry about.”

In the coming days Judi met with radiation oncologist, Benjamin Gielda, MD, who shared that she was a candidate for intraoperative radiation therapy (IORT) – a new treatment for breast cancer that delivers radiation at the time of surgery, following tumor removal.

“Dr. Gielda explained my options to me and told me I could receive three weeks of radiation after surgery or have a single dose during surgery with IORT – it seemed like an ideal situation,” said Judi. “I did some research on my own and IORT just seemed so practical and efficient.”  

A few weeks later her general surgeon performed lumpectomy surgery to remove the cancerous cells in Judi’s breast. While still in the operating room, Dr. Gielda delivered a dose of radiation directly to the tumor bed. Judi said she expected to be in pain after the procedure and was shocked at how little discomfort she felt.

“If it’s possible for cancer to be a positive experience, this was it,” she said. “I just keep saying I am one of the luckiest people – everything went so smoothly.”

Throughout the entire process Judi also had the support of her two daughters. One of whom lived in Chicago and, prior to the procedure, advised her mom to look into receiving care in a bigger city.

“I told her I felt really comfortable with my care team at the cancer center and I wanted to stay local,” said Judi. “After the surgery her mind was definitely changed and she told me she didn’t think I could have gotten better care anywhere else.”

Since the procedure Judi said her life hasn’t missed a beat. She continues to spend time with her daughters and enjoys walking their dogs near Lake Michigan.

“My biggest piece of advice for all women is to get a mammogram every year,” said Judi. “They’ve come so far with technology and the fact that they could discover and successfully treat a spot as small as mine is just amazing.”
