Cancer Epidemiology
Cancer epidemiology is the study of the causes, patterns, and frequency of malignant diseases within specific populations. It provides clinicians with essential tools for assessing cancer risk, guides the development of screening strategies for high-risk groups, and evaluates the effectiveness of preventive measures. Risk factors for cancer include genetic predisposition, immunosuppression, and environmental exposures, and may also arise from a previous history of viral infections, treatments, or other malignancies.
