The Claim
Between 1999 and 2012, thyroid cancer mortality in South Korea remained stable despite a more than sevenfold increase in incidence, indicating that the increase in diagnoses is due to the detection of non-life-threatening tumors rather than an increase in aggressive disease.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In South Korea, more people were diagnosed with thyroid cancer between 1999 and 2012, but the number of people dying from it didn’t go up — which suggests doctors are just finding harmless lumps that wouldn’t have hurt anyone, not more dangerous cancers.
See the scientific wording
Thyroid cancer mortality in South Korea remained stable between 1999 and 2012 despite a more than sevenfold increase in incidence, indicating that the surge in diagnoses reflects detection of non-life-threatening tumors rather than a true rise in aggressive disease.
What the research says
1 studyDoctors in South Korea started using ultrasounds to check people’s thyroids even when they had no symptoms, and found lots of tiny, harmless lumps. Even though more people were diagnosed, the number of deaths didn’t go up—meaning the extra diagnoses weren’t saving lives, just finding things that wouldn’t have hurt them.
