Screening

Screening is often confused with prevention. But there is an important difference. Prevention happens before people develop a medical condition. It aims to completely prevent illnesses, or at least delay them for a few years. The aim of screening, on the other hand, is to detect already existing illnesses. The hope is that detecting an illness earlier will at least improve the chances of recovery. A word of caution, though: well-meaning advice does not always deliver on its promises.
