["Sociology of Health & Illness, Volume 43, Issue 1, Page 58-64, January 2021. ", "\nAbstract\nOverdiagnosis and overtreatment are increasingly discussed as a significant problem in contemporary healthcare but are yet to receive any significant sociological attention, over and above that which is arguably transferable from the medicalisation literature. Overdiagnosis and overtreatment are often constructed as problems best addressed by educating patients and clinicians, and improving the relationships between them. The emergence of tools seeking to support decision‐making and to facilitate patients' asking questions about whether interventions are really necessary supports this conceptualisation. This article questions whether significant traction on overdiagnosis and overtreatment is possible through these means alone, arguing that even when professionals and patients may wish to do less rather than more, the system within which care is delivered and received can make this challenging to achieve. Drawing on Scott's (Sociology, 2018, 52, 3) ‘sociology of nothing’, the article demonstrates that a sociological perspective on overdiagnosis and overtreatment recasts them as issues that must be understood as a consequence of the organisational, financial and cultural attributes of the system, not just individual interactions, and advances a research agenda for the area.\n"]
