1. Identifying risk factors: Large-scale studies can identify new risk factors and confirm known ones. 2. Monitoring trends: Epidemiological surveillance can track the incidence and prevalence of various cancers, helping to identify emerging public health threats. 3. Evaluating prevention and treatment strategies: Data can assess the effectiveness of screening programs, vaccinations, and other interventions.
