Cancers of the nasal cavity and paranasal sinus cavities are rare, with only about 2,000 cases in the United States each year. Symptoms and signs of these types of cancer can also indicate other medical problems; thus, having them checked out by a doctor is always a good idea.
The nasal cavity and paranasal sinuses are lined by mucosa, a layer of mucus-producing tissue. The mucosa has many types of cells including squamous, glandular, nerve, blood vessel and infection-fighting cells. Any of these cells can become cancerous, with each type of cancer growing differently.
