Cancer Prevention Study-3 (CPS-3)


What if you could prevent even one family from hearing the words "you have cancer"? This year, you can fight back against cancer by enrolling in the American Cancer Society's new research study called the Cancer Prevention Study-3 (CPS-3).

The study is open to anyone who:

  • Is willing to make a long-term commitment to the study, which involves completing periodic follow-up surveys at home
  • Is between 30 and 65 years old
  • Has never been diagnosed with cancer (not including basal or squamous cell skin cancer)

By joining CPS-3, you can help researchers better understand the genetic, environmental and lifestyle factors that cause or prevent cancer, which will ultimately save lives.

Enroll in CPS-3

How Can You Participate?

As a part of enrollment, you will be asked to:

  • Read and sign an informed consent form
  • Complete a comprehensive survey packet that asks for information on lifestyle, behavioral and and other factors related to your health
  • Have your waist circumference measured
  • Give a small blood sample (similar to a doctor's visit - 7 teaspoons total). The blood sample will be drawn by a trained, certified phlebotomist

Upon completion of these two steps, the Society will send periodic follow-up surveys to update your information and annual newsletters with study updates and results.
