Chapter 4: Primary Prevention
Primary Prevention: Preventing Cancer Before It Starts
Primary prevention reduces cancer risk by minimizing harmful exposures and decreasing unhealthy behaviors before cancer develops. These include limiting tobacco use, promoting daily healthy food choices and regular exercise, expanding access to cancer-preventing vaccines and obesity treatment medications, limiting harmful sun exposure, reducing alcohol intake, and minimizing exposure to environmental toxins through equitable policy, systems, and environmental approaches.
- Tobacco: Making commercial tobacco use less desirable, acceptable, and accessible, especially among youth and underserved groups, helps prevent cancer and decreases health disparities. Targeted health campaigns, equitable tobacco prevention policies, and cessation programs reduce cancer risk from tobacco use.
- Nutrition and Physical Activity: Promoting regular physical activity and daily healthy food choices lowers the risk of related cancers and improves immune system functioning. Supportive environments that prioritize regular physical activity and daily healthy food choices, and access to obesity treatment options are important.
- Vaccines: Increasing Human Papillomavirus (HPV) and hepatitis B vaccinations by raising awareness, increasing access, and ensuring healthcare providers recommend them, protects against cancers caused by these viruses.
- Sun Safety: Preventing skin cancer means reducing ultraviolet exposure. Public education, sunscreen access, and discouraging indoor tanning help achieve this goal.
- Environmental Toxins: Limiting environmental exposure to cancer-causing substances through awareness and environmental policy change is essential, especially for vulnerable communities.
- Alcohol: Reducing alcohol use lowers the risk of several cancers. Education, screening, community support and policies help lower alcohol consumption and prevent alcohol-related cancers.
By taking action on these fronts, California can reduce cancer risk and create healthier communities.
