Cancer Prevention Study - 3 (CPS-3)
Research today for a cancer-free tomorrow.
You can join the movement for more birthdays and fight back against cancer by enrolling in a new research study called the Cancer Prevention Study - 3 (CPS-3). The American Cancer Society’s Epidemiology Research Program is inviting men and women between the ages of 30 and 65 years who have no personal history of cancer to join this historic research study. The ultimate goal is to enroll 500,000 adults from various racial/ethnic backgrounds from across the U.S. By joining CPS-3, you can help us understand how to prevent cancer, which will save lives and give people more of their most precious resource: time. More time with their families and friends, more memories, more celebrations...and more birthdays.
Study enrollment opportunities will take place at various venues in select communities across the United States and Puerto Rico.

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.
