Overdiagnosis can mean either:
- The diagnosis of a disease at an asymptomatic stage when it would not have had a chance to become symptomatic because the patient died in between.
- The false positive result of the application of diagnostic criteria that would not have given symptoms during the lifetime of a patient.
Screening programs increase both kinds of overdiagnosis.
