Cancer Prevention Study-3 (CPS-3)

Since the 1950s, more than 2.5 million dedicated study participants have joined the Cancer Prevention Studies, and their commitment to these vital research efforts has helped us better understand what causes cancer so that we can ultimately prevent it.

CPS-3 Enrollment Vol Part Numbers GraphIn December 2013, the American Cancer Society completed the initial recruitment of it's newest study, Cancer Prevention Study-3, with over 304,000 participants. The American Cancer Society's Epidemiology Research Program invited men and women between the ages of 30 and 65 years who had no personal history of cancer to join this historic research study. The ultimate goal was to enroll at least 300,000 adults from various racial and ethnic backgrounds from across the United States and Puerto Rico.

The successful completion of this enrollment was built on the partnership of Society staff and over 30,000 volunteers with enrollments being conducted at over 800 Relay For Life events, 100 Society events including Making Strides Against Breast Cancer and over 2,000 corporate, hospital and community partner hosted events.CPS-3 has participants from all over the United States and Puerto Rico with average age at enrollment of 47 years.

Now that we have completed the initial recruitment of our participants, we will be shifting our efforts to the next phase of the study called follow-up, which includes our first follow-up survey for the entire population. Participants can expect to receive this survey in May 2015. In addition to our follow-up survey, a small group of CPS-3 participants will be invited to participate in one of two sub-studies that we will be conducting this year on diet, physical activity, light and sleep patterns. These sub-studies are an essential component to maintaining the highest scientific standards in our study.

Participants can also look forward to receiving our annual newsletter in Spring 2015, that will be filled with information on Cancer Prevention Study-3 updates and research highlights from our other Cancer Prevention Studies.
