Impact of Diaphragmatic Breathing Coaching on Deep Inspiration Breath Hold Reproducibility and Organ Protection

"If participants are found to be eligible to take part in this study, participants will be randomly assigned (as in the flip of a coin) to 1 of 2 study groups: the Standard Patient Education group or the Breathe Radiation Protocol Coaching group. This is done because no one knows if one study group is better, the same, or worse than the other group.~If participants are in the Standard Participants Education group, participants will receive standard of care participants education."

If participants are in the Breathe Radiation Protocol Coaching group, participants will have access to a video that helps guide participants through a relaxed breath hold for the radiation treatment and also access to a coach for questions about the breathing process during radiation. This coaching will take place in the week before participants undergo radiation planning.
