Which of the following is not true about juvenile angiofibroma 
Select and explain. 
A. Biopsy for diagnosis, B. Benign tumor, C. Surgical excision, D. Second decade
A: Biopsy for diagnosis
Answer: A: Biopsy for diagnosis 
Explanation: Diagnosis is mostly based on the clinical picture. Biopsy of a tumour will present with profuse bleeding and is, therefore, avoided. If it is essential to differentiate it from other tumours, a biopsy can be done under general anaesthesia with all arrangements to control bleeding and transfuse blood.
