About CPS-3

CPS-3 is a grassroots effort where local communities from across the country can support cancer research not just through fundraising efforts, but also by participating actively in this historic research study. The goal of CPS-3 is to better understand the factors (lifestyle, environmental, genetic) that cause or prevent cancer and, ultimately, to help eliminate cancer as a major health concern for future generations.

Study participants will be asked to: read and sign a consent form, complete a survey, have their waist measured, and give a small blood sample (similar to a doctor’s visit). At home, participants will receive periodic follow-up surveys and research updates through annual newsletters.

We begin the study by collecting information on various exposures from individuals who do not have cancer and we continue to update this information over time. Participants will be followed for at least 20 years. This means that once you are enrolled we will be contacting you every two years with mailed questionnaires for you to answer. While you may be in the study for many years, we expect the amount of time it will take you to answer a questionnaire to be minimal (about 45 minutes for the follow-up questionnaires).

As cases of cancer or other diseases develop, we will compare those participants who develop cancer with those participants who do not. By doing so, we are able to understand the differences (in lifestyle, environment, and genetic factors) between people who get cancer and those who do not, what the likely risk factors are for cancer, and how to best prevent disease in the future.
