Deep breathing exercises to protect lungs during lung cancer treatment

This trial is testing whether incentive spirometry—a simple device that encourages you to take deep, controlled breaths—can help protect your lungs during intensive lung cancer treatment. Researchers want to see if regular deep breathing exercises can reduce inflammation and scarring of the lungs that sometimes occurs as a side effect of chemotherapy and radiation.

Lung cancer patients undergoing chemotherapy and radiation often experience serious lung complications like pneumonitis (lung inflammation) and scarring, which can harm their quality of life and breathing. This medication has shown promise in helping patients recover after surgery, but doctors want to test whether it can prevent these complications from happening in the first place during active cancer treatment.
