(NewsNation) — Intraoperative radiation therapy is a faster, less invasive and often cheaper treatment for breast cancer that is common in Europe and Asia; however, access remains limited in the U.S.

IORT was approved by the Food and Drug Administration in 1999 and involves just a single dose of radiation to a patient's breast tissue following surgery, which contrasts with other radiation treatments that often require multiple sessions and cost more.

"IORT offers the same benefits as other types of radiation therapy in just one treatment session," according to the Cleveland Clinic.
