OVERDIAGNOSIS Meaning and
Definition
-
Overdiagnosis refers to the identification or diagnosis of a disease or condition that would not have caused harm or symptomatic illness during a person's lifetime. It occurs when medical tests, screenings, or procedures detect abnormalities or inconclusive findings that lead to unnecessary treatment or interventions. Overdiagnosis stems from the increased sensitivity and advancements in medical technology and diagnostics, which may detect minor deviations from the norm that have little or no clinical significance.
Significant contributors to overdiagnosis include routine screenings, such as mammograms or prostate-specific antigen (PSA) tests, which may identify abnormalities that would not have caused serious health issues if left undetected. Additionally, the expansion of disease definitions and diagnostic criteria might also contribute to the overdiagnosis phenomenon.
Overdiagnosis can lead to several adverse consequences, both on an individual and societal level. These may include unnecessary medical procedures, exposure to potential harms associated with treatments (such as surgical complications or adverse drug reactions), psychological distress, and increased healthcare costs. Overdiagnosis can also divert resources from patients who truly need medical attention, potentially compromising the overall quality of healthcare delivery.
Addressing overdiagnosis requires a careful balance between early detection and avoiding unnecessary interventions. This involves critically evaluating the potential benefits and harms of diagnostic tests and screening programs, improving the accuracy of diagnostic criteria, and facilitating informed decision-making among healthcare providers and patients.

Etymology of OVERDIAGNOSIS
The word "overdiagnosis" is formed by combining two root words: "over" and "diagnosis".
1. "Over" is a prefix derived from Old English and has Germanic origins. It means "excessive" or "beyond". It is commonly used to indicate an excess, surplus, or exaggeration of something.
2. "Diagnosis" originates from the Greek word "diagnōsis", which consists of "dia-" meaning "apart" or "through", and "gnōsis" meaning "knowledge". The word was first used in English medical contexts in the early 17th century and refers to the identification of a disease or condition through a thorough examination or investigation.
By combining these two words, "overdiagnosis" has been coined to define the situation where a disease or condition is diagnosed more frequently or earlier than necessary, potentially leading to unnecessary treatments or interventions.
