Diagnosis and Treatment - early detection and treatment, regular exams and routine screenings.

• A. Primary Prevention
• B. Tertiary Prevention
• C. Secondary Prevention
• D. Communicable Disease

Answer: (C)

Secondary prevention focuses on detecting disease early, often before symptoms appear, so timely treatment can prevent progression and reduce complications. Regular exams and routine screenings fit this idea because they uncover conditions in their subclinical stages (like breast cancer with mammography, colon cancer with colonoscopy, or hypertension with blood pressure checks), allowing treatment to stop or slow the disease before it causes more harm.

Primary prevention aims to stop the disease from developing in the first place (vaccines, lifestyle changes). Tertiary prevention comes after a disease is established and aims to lessen damage and improve function (rehab, chronic disease management). Communicable disease is a type of illness, not a prevention level.
