Many Americans are undergoing needless thyroid biopsies, researchers say, and simplifying clinical guidelines would go a long way toward curbing the problem.
The investigators from University of California, San Francisco analyzed the medical records of about 8,800 patients who underwent thyroid ultrasound scans. Reporting in the Aug. 26 online issue of JAMA Internal Medicine, they said that more than 98 percent of the thyroid nodules found in patients were not cancerous.
"Right now, we're doing far too many thyroid biopsies in patients who are really at very low risk of having thyroid cancer," study lead author Dr. Rebecca Smith-Bindman, a professor in the department of radiology and biomedical imaging, said in a UCSF news release.
