Substudies & Tools

In addition to the triennial follow-up surveys we send, we also invite CPS-3 participants to volunteer for substudies, which allow smaller cohorts to collect more detailed information for more targeted research about specific risk factors for cancer, such as physical activity.

How CPS-3 Participants Are Contributing to Cancer Research

Many studies published by P站视频 researchers and other researchers across the United States use data from the Cancer Prevention Studies (CPS-II and CPS-3) and substudies.?

Here are some recent articles on cancer.org that describe such studies. We couldn't have made these findings without participants who took the time and made the effort to answer surveys, wear accelerometers, and supply samples of blood, urine, and saliva.
