Nasopharyngeal cancer infiltrative type is not easy to detect.
When the tumor of submucosal infiltrative type of nasopharyngeal cancer grows, the mass enlarges and pushes the mucosa and submucosal tissues to bulge into the nasopharyngeal cavity, and it is asymmetrical from left to right. As the tumor stimulates the surrounding tissues to show inflammatory proliferation and infiltration, some cases will be found to be inflammatory tissues when pathological examination is done, so they will often be missed and misdiagnosed, and it is necessary to take pathology for several times before the diagnosis may be confirmed.
Nasopharyngeal carcinoma can be categorized into nodular type, cauliflower type, ulcerative type and submucosal infiltration type. The submucosal infiltration type has the closest relationship with the surrounding tissues, and can often compress or block the pharyngeal opening of the Eustachian tube, causing tinnitus, occlusion of the ear and hearing loss on the affected side, leading to secretory otitis media, and clinically, many patients are found because of the ear symptoms at the clinic.
