Cases and Controls
A case-control study compares two groups of people: those with the cancer under study (cases) and those who do not have the cancer (controls). Researchers compare the genetic, environmental, lifestyle, and medical histories of the people in the two groups to identify factors associated with cancer.
Selected examples of DCEG case-control studies:
Breast, Ovary and Endometrial Cancer Studies in Poland
Case-control Studies of Renal Cell Cancer
- Renal Cell Cancer among Caucasians and African Americans in the United States
