The Cancer Prevention Study is a research initiative aimed at understanding the causes of cancer and identifying ways to prevent it. Conducted by the American Cancer Society, this study collects data from participants regarding their lifestyle, diet, and health history. The findings help researchers identify risk factors associated with different types of cancer. Participants in the study are typically asked to complete surveys and provide biological samples over time. This long-term research allows scientists to track changes and trends in cancer incidence, ultimately contributing to public health recommendations and cancer prevention strategies.
