A recent study led by researchers at the Clayman Thyroid Center, Tampa, Florida found that ultrasound screening identified thyroid cancer in asymptomatic women at rates higher than some established cancer screening methods.
The study, published in Annals of Endocrinology, Diabetes and Metabolism, analyzed data from a community-based screening program conducted between August 2022 and June 2024. Researchers evaluated 548 women aged 30 and older with no known thyroid disease or symptoms.
Among participants, 54% had previously undiagnosed thyroid nodules measuring at least 1 centimeter, while 16% had nodules considered suspicious for malignancy. Thyroid cancer was diagnosed in 2.4% of those screened, with all cases identified as papillary thyroid carcinoma.
By comparison, the study notes that fewer than 1% of Pap smears detect cervical cancer at the time of testing, and about 0.5% of mammograms detect breast cancer.
Lead author Dr. Rashmi Roy said the findings suggest ultrasound screening can detect thyroid cancer early, often before symptoms appear. Researchers also reported that cancers identified through screening were typically at an early stage, allowing for less extensive treatment. None of the patients required complete thyroid removal or radioactive iodine therapy, and 62% did not need lifelong hormone replacement.
The study reflects outcomes from a community screening initiative aimed at improving access to thyroid evaluation. Researchers noted that further studies are needed to determine whether routine screening should be more widely recommended.
