  Nasopharyngeal cancer
Cancer of the nasopharynx is a disease in which cancer (malignant) cells are found in the tissues of the nasopharynx.
The cancer is in the nasopharynx or has spread to the nose, the nasopharynx, or the bone or nerves in the head.
Treatment for cancer of the nasopharynx depends on where the cancer is in the nasopharynx, the stage of the disease, and the patient's age and overall health.

 Nasopharynx Cancer
The top of the nasopharynx is called the "cribriform plate", which is a sieve-like structure that transmits the nerves for smell to the brain.
The back of the nasopharynx is next to the "cavernous sinus", an area close to the brain through which important blood vessels and nerves travel.
Cancer of the nasopharynx is primarily prevalent in immigrant Chinese and slightly less prevalent in first-generation Chinese Americans.

Stage IIA: Cancer has spread from the nasopharynx to the oropharynx (the middle part of the throat that includes the soft palate, the base of the tongue, and the tonsils), and/or to the nasal cavity.
Stage IIB: Cancer is found in the nasopharynx and has spread to lymph nodes on one side of the neck, or has spread to the area surrounding the nasopharynx and may have spread to lymph nodes on one side of the neck.
Stage IVA: Cancer has spread beyond the nasopharynx and may have spread to the cranial nerves, the hypopharynx (bottom part of the throat), areas in and around the side of the skull or jawbone, and/or the bone around the eye.

Three sterile, dry, cotton-tipped swabs were used to take samples from each volunteer: one from the nasopharynx (through the mouth and swept up behind the uvula), one from both tonsils, and one swab of saliva between the lower gum and lips.
Of the 44 carriers with positive swabs from both nasopharynx and tonsils, each pair of isolates was considered to be phenotypically indistinguishable by serogroup, serotype, and sero-subtype.
Although duplicate swabs from the nasopharynx sometimes yield different meningococcal strains (3), none of the paired isolates in this study were distinguishable by phenotype.
