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.
