Summary
Brief summary (as posted)
This is a prospective observational study designed to determine the feasibility and acceptability of objectively measuring physical activity, sedentary time, and sleep using the Fitbit Charge HR wristband. 50 patients who have been diagnosed with breast cancer and are planning to initiate chemotherapy will be invited to participate in this study, and we will measure general and breast-specific quality-of-life using Patient-Reported Outcomes Measurement Information System (PROMIS) measures for 3-6 months after completion of chemotherapy.
