Cancer Prevention Study II (CPS-II)
The Cancer Prevention Studies (CPS) aim to understand why and how certain people develop cancer while others remain cancer-free. In 1982, the CPS-II cohort was established and includes approximately 1.2 million men and women, aged at least 30 years, recruited by American Cancer Society (ACS) volunteers in all 50 states of the United States of America and Puerto Rico. Participants have been followed biannually for mortality. The CPS-II Nutrition Cohort was established as a subgroup of the larger CPS-II cohort, in which approximately 185,000 individuals have been followed biennially for cancer incidence, diet, and other exposures, since 1992. The CPS-II Lifelink Cohort/Biorepository was initiated in 1998, and collected blood samples from 40,000 participants and cheek cell samples from 70,000 participants in the CPS-II Nutrition Survey cohort.
