A 45-year-old woman undergoes routine mammography. A small, non-palpable breast lesion is detected and confirmed as early-stage carcinoma. This detection represents which level of disease prevention?

• A Secondary prevention ✓
• B Primary prevention
• C Primordial prevention
• D Tertiary prevention

Explanation

Secondary prevention involves early detection and treatment of existing disease before symptoms appear. Mammography screening detects cancer at a pre-clinical stage, fitting this definition. Primordial prevention targets risk factor emergence, primary prevention prevents disease onset, and tertiary prevention reduces complications from established disease.
