C11: Malignant neoplasm of nasopharynx

Malignant neoplasm of the nasopharynx, commonly referred to as nasopharyngeal cancer, refers to a group of cancers that originate in the nasopharynx - the upper part of your throat behind your nose. The specific characteristics of these cancers can vary, but they generally involve abnormal, uncontrolled cell growth. The exact cause is usually unknown, but certain factors such as exposure to the Epstein-Barr virus, intake of certain preservative-rich foods, or a genetic predisposition may increase the risk of developing this condition. Common symptoms often include hearing loss, frequent ear infections, headaches, and nosebleeds. As the disease progresses, it may cause facial pain, double vision, or difficulty speaking. The disease predominantly affects the respiratory system but can spread to other systems, which can result in wider complications. The progression and severity of symptoms may vary widely depending on the exact type and stage of the neoplasm.
