The goal of this study is to compare an intervention that uses active games versus an intervention uses pedometer to encourage physical activity such as walking within breast cancer survivors in active cancer treatment. The study will include breast cancer survivor between the ages of 18 - 70 whom currently gets less than 150 minutes of planned physical activity per week and received a breast cancer diagnosis within 0 to 6 months. Participants will be randomized to participate in the support group using the active video game-based physical activity intervention (Wii and Xbox active games) or to participate in the existing UTMB breast cancer support group with pedometers (Digi-Walker CW-700/701). The investigators hypothesize that by engaging in active video gaming, breast cancer survivors will be motivated to initiate and maintain physical activity during treatment. This will ultimately increase functional capacity and prevent functional disability in breast cancer survivors.
