Participate in Cancer Prevention Study-3 (CPS-3)
If you've ever known someone with cancer, you know that birthdays are a very significant milestone.
There are nearly 13.7 million people in America who have survived cancer and countless more who have avoided it - who will be celebrating birthdays this year. 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 at least 300,000 adults from various racial and ethnic backgrounds from across the US. 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.
Research study enrollment opportunities will take place at various venues in select communities across the United States and Puerto Rico. For more information about CPS-3 and the selected enrollment locations, please email CPS3@cancer.org or call toll-free 1-888-604-5888.
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.
