epidemiology of cancer

Epidemiology of cancer studies how often and where cancers occur in populations, helping identify risk factors and patterns. Factors like genetics, lifestyle choices (such as smoking, diet, and activity levels), environmental exposures, and infections influence cancer risk. Understanding these patterns allows public health efforts to target prevention, early detection, and treatment strategies more effectively. Cancer incidence varies by age, sex, geography, and socioeconomic status, with some types more common in certain groups. Overall, ongoing research aims to reduce cancer's burden by identifying causes and improving interventions.
