Summary

This study tested whether mental exercises or a slowed clock can help people hold their breath longer during breast cancer radiation therapy. 36 healthy volunteers were asked to hold their breath while doing a simple mental task on a tablet. The goal was to see if these tricks could make breath holds easier and more comfortable, potentially improving treatment accuracy.
