Ear pain is one symptom of cancer of the pharynx, which extends from behind the nose to the openings of the esophagus and trachea, according to the National Cancer Institute and MedicineNet. This pain is also a sign of cancer of the larynx, or voice box.
Other signs of pharynx cancer include ringing ears and difficulty hearing, the NCI explains. Throat symptoms include problems talking and persistent neck or throat pain. Some individuals with pharynx cancer have recurrent headaches or breathing issues. Another indication of larynx cancer is pain when swallowing.
These two diseases fall into the category of head and neck cancers, says the NCI. These cancers typically develop in cells that line the interiors of the mouth, nose and throat.
