1. Early Detection: Identifying diseases at an early stage can significantly improve treatment outcomes. For example, regular mammograms can detect breast cancer early, increasing the chances of successful treatment. 2. Prevention: Routine screenings can prevent the onset of diseases by identifying risk factors and enabling lifestyle changes or medical interventions. 3. Reduction in Healthcare Costs: Early detection and prevention can reduce the long-term costs associated with treating advanced diseases. 4. Public Health: Regular checks contribute to public health surveillance, helping to track the spread of infectious diseases and monitor the effectiveness of vaccination programs.
