Pedal power: lung cancer patients try Pre-Radiotherapy exercise

This study tests whether a 20-minute exercise session on a stationary bike, done right before each radiotherapy treatment, is practical and safe for people with stage I-III non-small cell lung cancer. About 30 participants will try the program, and researchers will track how many join, attend, and complete the exercises. The goal is to see if this approach is acceptable and could improve quality of life.
