Overdiagnosis is a major driver of the thyroid cancer epidemic

18 August 2016 – A new report by the International Agency for Research on Cancer (IARC) in collaboration with the Aviano National Cancer Institute in Italy shows that the growing epidemic of thyroid cancer reported in recent decades in several high-income countries is largely due to overdiagnosis (i.e. the diagnosis of tumours that are very unlikely to cause symptoms or death during a person’s lifetime).

The article, published today in The New England Journal of Medicine, used high-quality cancer registry data from IARC’s reference publication Cancer Incidence in Five Continents to estimate the number of overdiagnosed cases of thyroid cancer in 12 countries (Australia, Denmark, England, Finland, France, Italy, Japan, Norway, Republic of Korea, Scotland, Sweden, and the USA).

Full report is here.
