Nasopharyngeal cancer refers to a group of malignant tumors originating in the mucosa of the upper respiratory tract and upper digestive tract. This includes the oral cavity, pharynx or oropharynx (including the base of the tongue and tonsils), upper trachea (larynx), nasopharynx, nasal cavity and sinuses, as well as tumors of the salivary glands.
The most common type in this group is squamous cell carcinoma.
Men over 50 are at the highest risk, with a strong correlation between disease incidence and smoking or alcohol use. In recent decades, an additional risk factor in Western countries (especially the U.S. and Europe) has emerged — the human papillomavirus (HPV). This form of cancer is more common in non-smoking men aged 30–50.
