Over diagnosis of thyroid cancers is an issue in the US, can you tell us more about this?
Many thyroid nodules are being discovered on imaging tests (CT, MRI, ultrasound) done for other purposes. Most of these so-called incidentalomas are benign, but a biopsy or surgery may be needed to show that they are not malignant. Even cancerous nodules tend to have an indolent course, especially if they are small. The authors of a 2016 paper in the New England Journal of Medicine stated that overdiagnosis accounted for 70% and 45% of cases in men between 2003 and 2007.
