Importance of Screening and Diagnostic Tests in Cancer Prevention

Cancer remains one of the leading causes of mortality worldwide. Early detection through screening and diagnostic tests significantly improves treatment outcomes.

Why Screening Matters

Screening tests help detect cancer before symptoms appear, increasing the chances of successful intervention.

Common Screening Tests

• Mammography: Used for early detection of breast cancer.
• Pap Smear: Detects cervical cancer at an early stage.
• Colonoscopy: Helps identify colorectal cancer and polyps.
• Low-Dose CT: Used for lung cancer screening in high-risk patients.

Diagnostic Testing for Confirmed Cases

Once abnormalities are detected, diagnostic tests such as biopsies and advanced imaging help confirm and stage the disease.

Benefits of Early Detection

• Improved survival rates
• Less aggressive treatment options
• Reduced healthcare costs

Regular screening enhances early intervention and significantly reduces cancer-related mortality.
