It is meaningless to evaluate the probability of developing nasopharyngeal cancer based on simple nasopharyngeal elevation. Nasopharyngeal cancer can be of nodular, cauliflower, infiltrative, ulcerative, and submucosal types, and there is no detailed classification of the probability of developing nasopharyngeal mucosal elevation involving the above mentioned characteristics. The detection of nasopharyngeal mucosal elevation should be analyzed according to different individuals and manifestations in different populations.
Nasopharyngeal bulge is a soft tissue proliferation in the nasopharynx, which can be benign or a characteristic manifestation of nasopharyngeal cancer. For nasopharyngeal bulge, nasopharyngoscopy should be performed, which can directly observe the surface of the bulge, determine whether the mucosa is smooth, whether there is erosion, congestion, etc., which can have a certain role in suggesting the nature of the lesion.
Usually, chronic inflammatory hyperplasia or adenoid residue, its surface may be smoother, if it is a prolonged ulceration, or even a pseudomembrane formation, more suggestive of the possibility of malignancy. In some cases of submucosal nasopharyngeal carcinoma, even through several suspicious histopathologic examinations, the characteristics of cancerous tissue cannot be found accurately.
However, pathologic examination is still needed to confirm whether a nasopharyngeal bulge is cancerous, a benign growth, or a chronic inflammatory reaction. Simply counting the number of cases of nasopharyngeal cancer in nasopharyngeal mucosal elevations has no scientific value or practical clinical significance in an objective medical evaluation system.
