In cancer survivors activity levels have been studied primarily by means of questionnaires, while objective information on actual daily activity levels and their distribution throughout the day is lacking. The findings of this study suggest that especially cancer survivors who received chemotherapy as part of their treatment, have low physical activity levels. However, this study did not found support for a deviating daily activity pattern in cancer survivors compared to healthy controls. Since information on daily activity patterns is important for the development of new interventions to improve post cancer activity behavior, additional research is needed to determine if a larger study sample supports the findings of this pilot study
