How is screening for nose cancer performed and who should be screened?
Screening includes a detailed history and an examination of the post nasal space which is an area at the back of the nose. This can be done with a mirror or more accurately by an endoscope. Special lighting during the examination also improves the detection of nose cancer.
Individuals with symptoms of neck lumps, nose bleed, blood stained sputum and hearing loss should be an ENT specialist. Individuals who have family members who have nose cancer should also go for regular checks.
