An In-Depth Guide to Intraoperative Radiation Therapy (IORT) for Breast Cancer Treatment

What is IORT Breast Cancer Treatment and How Does It Work?

Accelerated Partial Breast Irradiation (APBI) is a cutting-edge approach to breast cancer treatment that offers a more targeted and localized radiation therapy solution compared to traditional methods. Intraoperative Radiation Therapy (IORT) is a specific type of APBI that delivers a concentrated dose of radiation directly to the tumor bed during surgery.

During an IORT procedure, after the tumor is removed, a specialized device is placed inside the breast to deliver the radiation dose. This localized treatment approach allows for higher doses of radiation to be administered precisely to the affected tissue, while minimizing exposure to surrounding healthy tissue.

In essence, IORT offers a more efficient and personalized treatment option by delivering targeted radiation therapy directly to the site of the tumor in a single session, eliminating the need for multiple post-operative treatments.

Furthermore, IORT has been shown to reduce the risk of recurrence in certain breast cancer patients, making it a promising alternative for those seeking a more effective and convenient radiation therapy option.
