Official title
Effects of Bright Light on Co-occurring Cancer-related Symptoms in Breast Cancer Survivors: A Personalized Intervention
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will implement therapeutic bright light that is tailored to the individual's circadian typology and will estimate its effects on circadian rhythms, 4 common cancer-associated symptoms, and impact on quality of life in survivors living with cancer. Examining a selected phase marker (core body temperature) in relation to the associated clinical features (symptoms) is the starting point for future investigation of the biological mechanisms of symptoms.
