The US Preventive Services Task Force (USPSTF) recommends against screening for thyroid cancer in asymptomatic adults, giving the practice a grade of D.1 That is, the Task Force discourages use of screening with palpation or ultrasonography with a moderate degree of certainty that such screening has no net benefit or that the harm outweighs any benefits. The recommendation is based on a systematic evidence review2 that is an update of a prior USPSTF recommendation from 1996,3 which came to a similar conclusion.
