Active Breathing Coordinator

Treating breast cancer with radiation therapy can be challenging, because the tumor is a moving target move – shifting up and down as you breathe.

To solve this problem, you may be asked to use a device called the Active Breathing Coordinator. Similar in appearance to a snorkel, the ABC helps you hold your breath. And when your chest is not moving, it’s easier to deliver radiation directly to the breast tumor.

The ABC also limits radiation to the surrounding healthy tissue and organs. Most importantly, it protects the heart from the risks of radiation exposure.

Mercy’s doctors and cancer specialists use the ABC to make sure your radiation treatment is comfortable, safe and effective. It’s a proven, noninvasive technique that lets you take an active part in your care.
