What type of prevention does a breast cancer screening intervention represent?

  1. Tertiary prevention

  2. Advocacy

  3. Secondary prevention

  4. Primary prevention

The correct answer is: Secondary prevention

A breast cancer screening intervention exemplifies secondary prevention because it involves procedures aimed at detecting a disease in its early stages before clinical symptoms appear. The goal of secondary prevention is to identify individuals at risk for cancer, allowing for early intervention and treatment, which can significantly improve outcomes and survival rates. In the case of breast cancer, screenings such as mammograms are conducted to catch any anomalies early, facilitating timely management of the condition. In contrast, primary prevention focuses on preventing the onset of disease altogether through measures such as vaccinations or lifestyle changes, while tertiary prevention deals with managing and reducing the impact of an already diagnosed disease by preventing complications or further deterioration. Advocacy, while vital in public health, does not fit within the traditional prevention framework and often supports efforts in both primary and secondary prevention through education and policy changes.
