The signs and symptoms of sinus cancer include persistent nasal congestion that occurs on one side as well as pain in the forehead, nose and around the ear. Some patients experience recurrent ear infections and hearing difficulties. Blurred vision and frequent nosebleeds occur in some patients, reports Cedars-Sinai.
Sinus cancer may cause post-nasal drip at the back of the patient’s throat as well as growths in the face or neck. Pus may drain from the nose, and patients tend to have a decreased sense of smell or taste, according to the American Cancer Society. Patients' faces may feel numb or painful, and they may have constant runny eyes. Other symptoms include loosening or numbness of the teeth and bulging of one eye.
Some patients experience increased pressure in the ear, a lump on the roof of the mouth or the development of a lump in the nose that does not heal, according to the National Cancer Institute. The Cedars Sinai Medical Center states that many nasal or sinus cancers do not present symptoms, but certain persistent signs and symptoms indicate cancer. The American Cancer Society notes that most of these symptoms result from other conditions and having a medical examination is essential to determine their cause and treatment.
