This randomized pilot clinical trial studies active breathing coordinator-mediated radiation therapy to see how well it works compared with VisionRT-based deep inspiratory breath hold radiation therapy works in treating patients with breast cancer. Active breathing coordinator-mediated radiation therapy and VisionRT-based deep inspiratory breath hold radiation therapy are used to help minimize heart and lung radiation dose during radiation treatment. VisionRT-based deep inspiratory breath hold radiation therapy may work better in treating patients with breast cancer.

PRIMARY OBJECTIVES:
I. To quantify residual motion during deep inspiratory breath-hold using active breathing coordinator-mediated radiation therapy (ABC) and VisionRT-based deep inspiratory breath hold radiation therapy (VisionRT) during left post-mastectomy chest wall radiotherapy.
II. To determine clinical and dosimetric impact of residual motion, on heart and lung dose.
SECONDARY OBJECTIVES:
I. To compare time of simulation and daily treatment for deep inspiratory breath-hold (DIBH) with both ABC and VisionRT.
II. To evaluate DIBH reproducibility of both ABC and VisionRT DIBH.
OUTLINE: Patients are randomized to 1 of 2 groups.
GROUP I: Patients undergo ABC once daily (QD) for 30-45 minutes for 14 fractions and then VisionRT QD for 30-45 minutes for 14 fractions.
GROUP II: Patients undergo VisionRT QD for 30-45 minutes for 14 fractions and then ABC QD for 30-45 minutes for 14 fractions.
