The U.S. Preventative Services Task Force said in the news release that there is no evidence that screenings improve survival and can lead to over-diagnosis and other possible complications.
Task Force member Karina W. Davison, Ph.D., M.A.Sc., said:
“While there is very little evidence of the benefits of screening for thyroid cancer, there is considerable evidence of the serious harms of treatment, such as damage to the nerves that control speaking and breathing.
What limited evidence is available does not suggest that screening enables people to live longer, healthier lives.”
The Task Force said that over-diagnosis “leads to an increase in new diagnoses of thyroid cancer without affecting the number of people who die from thyroid cancer.”
Thyroid cancer is fairly rare in the U.S., according to the Task Force, which estimates there will be 56,300 news cases of the disease in 2017, accounting for 3.8% of all cancers.
The incidence of thyroid cancer has risen about 4.5% per year over the last decade, faster than any other cancer. However, the mortality rate has not risen and remains at about .05 deaths 100,000 people in 2013. [2]
Thyroid patients usually have a good prognosis, with a 5-year survival rate of 98.1%.
