August, 2025: We have previously proposed the circadian disruption hypothesis — that disturbances in the circadian system may be a key mechanism linking cancer and its treatment to fatigue, sleep problems, mood, and cognitive symptoms. Our latest 2025 longitudinal study in lung cancer patients undergoing immunotherapy provides empirical support. These findings strengthen the case for targeting the circadian system as a modifiable pathway to improve quality of life during cancer treatment- Link to full paper here: https://doi.org/10.1016/j.sleep.2025.106740
