Overdiagnosis is the diagnosis of disease that will never cause symptoms or death during a patient's ordinarily expected lifetime [1] and thus presents no practical threat regardless of being pathologic. Overdiagnosis is a side effect of screening for early forms of disease.
Overdiagnosis is the diagnosis of "disease" that will never cause symptoms or death during a patient's lifetime. [9] It is a problem because it turns people into patients unnecessarily and because it can lead to economic waste [10] (overutilization) and treatments that may cause harm. Overdiagnosis occurs when a disease is diagnosed correctly ...
Lead time bias occurs if testing increases the perceived survival time without affecting the course of the disease. Lead time bias happens when survival time appears longer because diagnosis was done earlier (for instance, by screening), irrespective of whether the patient lived longer.

As such, the committee recommended against screening and the Ministry of Health, Labor and Welfare decided to stop the screening program. [28] Another example of overdiagnosis happened with thyroid cancer: its incidence tripled in United States between 1975 and 2009, while mortality was constant. [29]
Gaps in accessing mental health care. The challenge lies in ensuring cancer patients and survivors actually have access to mental health care. Even getting an appointment can be difficult: ...
Overscreening is a type of unnecessary health care, so the causes of unnecessary health care are also causes of overscreening. Some causes include financial biases for physicians to recommend more treatment in health care systems using fee-for-service and physician self-referral practices; and physicians' practice of defensive medicine.
Length time bias in cancer screening. Screening appears to lead to better survival even when actually no one lived any longer. Length time bias (or length bias) is an overestimation of survival duration due to the relative excess of cases detected that are asymptomatically slowly progressing, while fast progressing cases are detected after giving symptoms.
