Ultrasound detected papillary projections in 78% of tumors. Papillary projections were disseminated in 33% of malignant, 20% of borderline, and 0% of benign tumors (p = 0.0049). The mean size of the papillary projections was 9.6, 15.7, and 35.3 mm in benign, borderline, and malignant tumors, respectively (p = 0.0007).
1 Papillary thyroid cancer is more common in females than in males by a 3:1 ratio. 2  The prognosis directly related to tumor size. ( 3 Less than 1.5 cm [1/2 inch] is a good prognosis.). 4  This cancer accounts for 85% of thyroid cancers due to radiation exposure. Peak onset ages are 30 to 50 years old. 2  Papillary thyroid cancer is more common in females than in males by a 3:1 ratio. 3  The prognosis directly related to tumor size.
