We also use the demographic information you submit to interpret the results of our research. Cancer Prevention Study-3 uses your contact information (such as name, email address, and postal address) to invite you to participate in Cancer Prevention Study-3 surveys and to link to state and national registries. Cancer Prevention Study-3 will not disclose your identity or any of your personally identifiable information without your authorization.

Data Security and Participant Privacy

We understand that data is valuable and work diligently to secure all data in order to ensure the long-term success of our study and to maintain the privacy, support, and confidence of our participants. Since CPS-3 began, we have made data security and privacy two of our top priorities. We continue to update our data security and privacy policies as technologies

Here are the steps we take to ensure data security and participant privacy:

  • Data are stored on secure servers.
  • Physical study materials are stored in locked facilities.
  • Personal identifying information (like name, date of birth, address, etc.) is stored separately from health and survey data and is accessible to only a limited number of CPS-3 staff.
  • Biospecimen samples (blood, tumor tissue, etc.) are stored in secure facilities and are labeled with a unique identifying number.
  • We do not share personal contact information with anyone without your consent.
  • CPS-3 staff complete regular biomedical research ethics training and have signed confidentiality forms.
  • Online data collection tools are hosted on secure sites and use servers that are compliant with the strictest industry standards.
  • Study results are presented in aggregate form. In other words, results will be presented as a group so individuals cannot be recognized.
  • Data collection and storage processes, as well as study activities, are reviewed by the Emory University Institution Review Board.
