One of the most powerful tools in public health is screening – whether for cancers like cervical or breast cancer, genetic abnormalities, or infectious diseases.
Screening can be transformational, detecting disease early and preventing it taking hold. It is, however, often useless and can be harmful, and its advantages are often exaggerated.
This talk will consider the situations where screening can help, where it does harm, and why these are usually predictable.
