Paranasal Sinus Cancer and Nasal Cavity Cancer
Nasal cancer occurs in the nose or the area behind the nose and toward the throat (nasal cavity). The paranasal sinuses are air-filled pockets in the bone surrounding the nose and nasal cavity. Squamous cell cancer is the most common form of cancer in this area. However, other types of cancer, including melanoma, sarcoma, and midline granuloma, can form here. So can benign tumors that can turn into cancer. Symptoms of a tumor in this area may be very similar to symptoms of noncancerous conditions: blocked sinuses; pain in the head, ear, or teeth; runny nose; nosebleeds; lump in the face or nose; numbness in the face; swelling; and double vision.
