Symptoms of paranasal sinus and nasal cavity tumors include persistent sinus congestion, nosebleeds, double vision, a nonhealing sore inside the nose and pain in the ear and upper teeth, according to the National Cancer Institute. However, such symptoms may not show in the early stages of the cancer when the tumor is small. Since these symptoms are nonspecific and may indicate other conditions, it is best to refer to a doctor for further testing and a clear diagnosis.
A paranasal sinus and nasal cavity cancer is a disease where the mucosa lining of the hollow cavities around the nose and the nasal cavity grows into malignant tumors, explains the National Cancer Institute. Examples of paranasal sinus and nasal cavity cancers include sarcoma, melanoma, midline granuloma and squamous cell carcinoma, the most prevalent form. A person is most likely to develop the tumors if he smokes, has a human papillomavirus infection, has a job that exposes him to dust and harmful chemicals and is a male over 40 years old.
Paranasal sinus and nasal cavity cancers are difficult to diagnose and cure because the tumors are only noticeable at an advanced stage without testing, states the National Cancer Institute. Doctors diagnose the tumors with a variety of tests including X-rays of the head and neck, magnetic resonance imaging (MRI) and a laryngoscopy.
