Interesting stuff - finding the balance between not missing important thyroid cancers, and not over-diagnosing thyroid cancers that are not likely to cause any ill-health, remains a challenge. Looks like Korea is moving towards a more conservative approach, more in line with the more typical international approach. Seems sensible to me.

I liked this story - a TV host in the US received a message from a concerned viewer, suggesting he get his visible thyroid nodule checked out. It turns out to be thyroid cancer, from which he is now doing well.

​Thyroid cancer diagnosis, from your armchair!
