Nodules >1 cm were considered benign if no abnormal cells (benign cytology) were found on an adequate FNA, if no evidence of cancer was found on histologic examination of the resected nodule, if thyroid scintigraphy indicated the nodule functioned autonomously, or if cystic, there was greater than a 50% reduction in nodule diameter on follow-up ultrasound. The mean nodule diameter was 2.6 cm, although 20%25% of the cohort (n = 1838 total nodules; n = 1771 evaluable) presented with nodules larger than 3 cm, and 11% (n = 794 total nodules; n = 773 evaluable) with nodules larger than 4 cm. Although most are benign, 10%-15% prove malignant. Elsevier; 2020. https://www.clinicalkey.com. Most thyroid nodules are benign, which means they arent cancerous.
