Quick Summary

Secondary prevention in medicine focuses on detecting and treating diseases in their early stages to prevent them from worsening or causing further complications. This approach is crucial for reducing the risk of disability and death.1

Key aspects include:
* Early Detection: Utilizing screening procedures to identify conditions like certain cancers, high blood pressure, and metabolic disorders before symptoms become apparent.12
* Intervention: Implementing effective measures once a condition is identified to halt its progression.12

This contrasts with primary prevention, which aims to prevent disease before it occurs, and tertiary prevention, which focuses on managing established diseases to improve quality of life and prevent further deterioration.1
