Sometimes, people with nasal cavity or paranasal sinus cancer do not show any of these symptoms. In fact, these types of cancer are usually diagnosed in their later stages because early-stage cancer typically does not cause any symptoms. Nasal cavity or paranasal sinus cancer is often discovered when a person is being treated for seemingly benign, inflammatory disease of the sinuses, such as sinusitis.
People with nasal cavity or paranasal sinus cancer may experience the following symptoms or signs.
# Nasal obstruction or persistent nasal congestion and stuffiness, which is often called sinus congestion
# Chronic sinus infections that do not respond to antibiotic treatment
# Frequent headaches or pain in the sinus region
# Pain or swelling in the face, eyes, or ears
# Persistent tearing of the eyes
# Bulging of one of the eyes or vision loss
# Decreased sense of smell
# Pain or numbness in the teeth
# Loosening of teeth
# A lump on the face, nose, or inside the mouth
# Frequent runny nose
# Frequent nosebleeds
