Nasal and paranasal tumors are abnormal growths that begin in and around the passageway between your nose and mouth (nasal cavity). Nasal tumors begin in the nasal cavity. Paranasal tumors begin in air-filled chambers around the nose called the paranasal sinuses.

Nasal and paranasal tumors can be noncancerous (benign) or they can be cancerous (malignant). Several types of nasal and paranasal tumors exist. Which type of tumor you have helps determine the best treatment for you.
