Bright idea: light and occupational therapy may beat cancer fatigue
NCT ID NCT05519878
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether light therapy and occupational therapy can reduce fatigue in people with genitourinary cancers (like prostate, kidney, or bladder cancer). About 224 adults on active cancer treatment will be assigned to receive light therapy, occupational therapy, both, or neither. The goal is to see if these low-cost, low-burden approaches improve quality of life by easing fatigue.
