cancer-related fatigue

Summary

Fatigue due to cancer and its treatment (for example, radiation therapy) can interfere with quality of life and can linger long after treatment has ended, yet research examining preventative approaches has produced limited clinical benefit. The proposed study will provide information about systematic light exposure for the prevention of fatigue in prostate cancer patients undergoing radiation therapy and will investigate how it works. This study would facilitate the development of this potential preventative treatment, giving health care providers and cancer survivors a much-needed tool to help with cancer-related fatigue.
