What size thyroid nodule is worrisome?
Nodular size of 1 – 1.9 cm was more prevalent among cancer patients than in benign cases (p<0.001). The highest malignancy risk was observed in nodules <2 cm and no increase in malignancy risk for nodules >2 cm.
How does thyroid cancer make you feel?

What size thyroid nodule should be biopsied?
According to the Society of Radiologists in Ultrasound, biopsy should be performed on a nodule 1 cm in diameter or larger with microcalcifications , 1.5 cm in diameter or larger that is solid or has coarse calcifications, and 2 cm in diameter or larger that has mixed solid and cystic components, and a nodule that has ...
