The purpose of this study is to determine how physical activity, other lifestyle factors, and psychosocial factors are related to quality of life and other health outcomes across the breast cancer survival spectrum from diagnosis to long term survival in a nationally representative sample of breast cancer patients and survivors across a 6 month period of time.

Participants in this study will be asked to sign an informed consent, wear an activity monitor (similar to a pedometer) for 7 consecutive days and complete a packet of questionnaires. The questionnaires will take about 45 minutes to complete. All materials will be sent to participants via the US Postal Service and will need to be mailed back in the provided self-addressed stamped envelopes within 2 weeks. Participants will be asked to repeat these same assessments again in 6 months. NO lab visits will be required for participation. Women from all across the U.S. who have been diagnosed with breast cancer at any point in their lives are being sought. There is no limit on time since diagnosis or treatment status.
