1. Epidemiological Research: PBCRs provide a foundation for epidemiological studies, allowing researchers to identify risk factors, evaluate screening programs, and understand cancer etiology. 2. Public Health Planning: Data from PBCRs enable public health authorities to allocate resources effectively, plan prevention and control programs, and monitor the impact of public health interventions. 3. Healthcare Services: They help in assessing the quality of cancer care and identifying disparities in healthcare access and outcomes among different population groups. 4. Survival Analysis: PBCRs facilitate the calculation of survival rates, which is critical for evaluating the effectiveness of treatment protocols and for clinical trials.
