Tracking Physical Activity Throughout Chemotherapy for Breast Cancer

Although there are many benefits of engaging in physical activity during cancer treatments, activity levels typically decline throughout treatment. Existing research has primarily relied on self-reported activity levels and only captured periodic snap shots or retrospective reports of activity levels, which are subject to recall bias. Exactly how activity levels change throughout chemotherapy is not known. This study will provide minute-by-minute level objective physical activity data across the entirety of the patient's chemotherapy treatments. This in depth data will provide a new perspective on the patterns of activity levels and help to identify if there are critical times in which to intervene to prevent declines in physical activity.

The investigators will assess the feasibility of the pre-treatment recruitment by documenting recruitment rates and participant acceptance of wearing the accelerometer.
