Preventive medicine aims to reduce risks factors that contribute to disease development and progression. Such practices are divided into primary (e.g., immunization), secondary (e.g., screening tests), and tertiary prevention (e.g., medical or surgical therapy, rehabilitation). The paradox of prevention is that the measures that benefit the population as a whole rarely benefit the individual.
