BreastScreen overdiagnosis risk is minimal: study
Amid calls for a review of the screening program epidemiologist Professor David Roder, of the University of South Australia, said the evidence for a screening benefit was overwhelming.
He analysed 50 studies to estimate the rate of overdiagnosis as a proportion of cancers diagnosed, finding it was commonly around 5–9% worldwide.
Applying overdiagnosis estimates to Australian breast cancer rates he found that for a woman aged 50–69 years attending BreastScreen the risk was between 0.6% and 2% over 20 years.
