Nasopharyngeal angiofibroma is a tumor that grows behind the nose. Although it is a benign tumor (not cancerous), it is aggressive and serious. It can spread from the nasal cavity to the sinuses, eye socket, skull and brain.
The nasopharyngeal angiofibroma tumor is made mostly of blood vessels, which can result in frequent nosebleeds. The condition is also called juvenile nasopharyngeal angiofibroma (JNA) because the vast majority of these tumors grow in adolescent males. Doctors also call it juvenile angiofibroma (JA).
Tumours need a consistent supply of blood in order to grow. Embolisation is a minimally invasive procedure performed by interventional radiologists, in which the blood supply to masses or vessels which are causing symptoms in a patient is cut off, relieving the symptoms the patient experiences.This involves using liquid, particles or microspheres to block blood vessels, redirecting blood flow away from the tumour. This causes the tumour to shrink and die.
