In the four-step model for cancer control, what is the third step?

• A. Identify the burden of cancer in geographic areas and by characteristics of person (measure)
• B. Implement the intervention plan
• C. Share this information with community organizations so they can target the areas and populations most in need and plan appropriate intervention strategies
• D. Measure whether the desired changes occurred

Answer: (B)

In this four-step model, the sequence moves from assessing need to planning with community input, then putting the plan into action, and finally evaluating the impact. The step that involves actually putting the intervention into practice is implementing the intervention plan. This is where programs are launched, resources are coordinated, activities are carried out, and the plan is executed as designed. Measuring outcomes occurs after implementation to see if the desired changes happened, while identifying burden and sharing information with community partners correspond to the planning and assessment phases.
