What is overdiagnosed cancer?
Abstract. Overdiagnosis occurs in a population when conditions are diagnosed correctly but the diagnosis produces an unfavourable balance between benefits and harms. In cancer screening, overdiagnosed cancers are those that did not need to be found because they would not have produced symptoms or led to premature death ...
Do doctors overtreat?

What is the prognosis for precancerous lesions?
Prognosis for precancerous lesions includes the risk of development of invasive cancer, the period over which such a tumor would develop, and the prognosis of that type of tumor should it occur. Prognosis for invasive cancer includes risk and timing of development of metastatic disease and death.
Is screening for cancer effective?
If a cancer is fast growing, screening is rarely effective. If a cancer is slow growing but progressive, with a long latency and a precancerous lesion (eg, colonic polyps or cervical intraepithelial neoplasia), screening is ideal and less frequent screening (eg, 10 years for colonoscopy) may be effective.
What is overdiagnosis in medical terms?
