Intrabeam therapy is a type of brachytherapy for breast cancer. After removing the tumor with surgery, your doctor uses a small probe to treat the area with radiation.

Intrabeam therapy takes less time and is more convenient than external beam radiation. External radiation for breast cancer can take five days a week for six weeks. With Intrabeam, you might have just one treatment after your doctor removes the tumor.

Intrabeam therapy causes fewer side effects than external beam radiation. Your doctor can send high-energy beams directly to the tumor area without going through healthy tissue.  

The OHSU Knight Cancer Institute is the only center in the Northwest offering Intrabeam therapy. Your doctor and healthcare team can help you decide if Intrabeam is right for you.
