Usually nasopharyngeal swelling can be ruled out or identified as nasopharyngeal cancer through medical history, clinical symptoms and pathological examination.
1. Medical history: research shows that nasopharyngeal cancer has family genetic history, which is mainly related to EBV infection, followed by heavy smoking, frequent eating of pickled food and air pollution.
2. Clinical symptoms: Typical symptoms of nasopharyngeal cancer include blood in the nasal mucus, nasal congestion, tinnitus, hearing loss, etc. In serious cases, symptoms such as facial numbness, diplopia, vision loss, hoarseness and enlarged cervical lymph nodes may also occur.
3. Examination: Through nasopharyngoscopy, small nodular or cauliflower-like neoplastic elevations can be found in the pharyngeal saphenous fossa and the posterior wall of the nasopharyngeal apex and indicate that they are rough and not fat. Secondly, hard, poorly mobile or inactive, painless enlarged lymph nodes can be detected by neck palpation. In addition, CT examination shows thickening and plumping of the mucosa of the left nasopharynx, and MRI examination shows nasopharyngeal neoplasm.
Ultimately, a nasopharyngeal neoplasm can be taken for examination to clarify the diagnosis. When the presence of nasopharyngeal swelling is found, it is necessary to go to the hospital in time to clarify the specific cause.
