From: Screening and overdiagnosis: public health implications

• Overdiagnosis is the diagnosis of a condition that is not associated with a substantial health hazard; it causes overtreatment.
• Screening is a major cause of overdiagnosis.
• Patients and physicians should be informed about risk of overdiagnosis associated with screening. Targeted screening, active surveillance, and prognosis estimation allow prevention of overdiagnosis and of overtreatment.
• Research is needed to assess the public health burden of overdiagnosis due to screening activity.
