Episode notes
Screening Detects Asymptomatic Risk
- Screening seeks to identify apparently healthy people at increased risk before symptoms appear.
- The goal is earlier intervention to alter disease trajectory or prevent complications.
From Mass To Targeted Screening
- Screening can be mass population-wide or targeted to higher-risk individuals (case finding).
- Medicine is shifting toward more targeted screening based on individual risk factors.
Screening Is A Recent, Evolving Practice
- Screening emerged mainly in the 20th century with TB X-rays and wartime programs.
- Harms of screening (false positives, anxiety) weren't widely recognized until decades later.
