Evaluating chronotypically tailored light therapy for breast cancer survivors: Preliminary findings on fatigue and disrupted sleep.

ABSTRACT: More than one-third of cancer survivors experience significant residual symptoms after treatment completion. Fatigue and sleep disruption often co-occur and exacerbate each other. The purpose of this preliminary analysis was to examine the effect of a chronotypically tailored light therapy on fatigue and sleep disruption in female survivors 1-3 years post-completion of chemotherapy and/or radiation for stage I to III breast cancer.
