NPC differs significantly from other cancers of the head and neck in its occurrence, causes, clinical behavior, and treatment. It is vastly more common in certain regions of East Asia and Africa than elsewhere, with viral, dietary and genetic factors implicated in its causation. It is most common in males. It is a squamous cell carcinoma or an undifferentiated type. less
Juvenile angiofibroma: a markedly vascular fibrous tumor occurring in the nasopharynx of males, usually in the second decade of life; epistaxis and local invasion may result, but spontaneous regression may occur after sexual maturity.

In inverted papillomas, these projections grow inward and into the underlying bone. These tumors are locally aggressive, often recur, and can become malignant (cancerous). Squamous cell carcinoma is the most common malignancy associated with inverted papillomas.Symptoms may include a runny nose, nasal obstruction, sinus infections, headaches, and facial pain. less

They are common and are not cancerous (that is, they are benign). Nasal polyps can vary greatly in size. There may be only one but sometimes several grow like a small bunch of grapes on a stem. In most cases the cause is not known. It is thought that ongoing (chronic) inflammation in the nose causes swelling (oedema) of the lining of the nostril. Due to gravity, this swelling hangs down (dependent oedema), forming the polyp. Polyps usually affect both nostrils and can gradually enlarge, blocking the nose.Polyps can also grow in the sinuses. The sinuses are air-filled spaces in the skull which drain into the nose. The biggest sinuses are called the maxillary sinuses. They are found under the eyes, behind the cheeks. The lining of the sinuses is the same as the lining of the nose, so this is why polyps can also form in the sinuses. less
