prevention

Reducing cancer risk at the population level by:

• eliminating or reducing exposure to things that cause cancer
• changing conditions that contribute to cancer (such as obesity or physical inactivity)
• tailoring individual risk strategy based on genetic testing results where possible
• using vaccines and drugs that stop cancer from developing

Prevention requires healthy lifestyle changes and healthy public policies and programs that create supportive, health-enhancing environments and access to prevention interventions. It includes primary, secondary and tertiary prevention.
