Hearing loss related to nasopharyngeal cancer tends to only occur in one ear. When you have a head cold, it's sometimes hard to tell if the main problem is in your ear, nose, or throat. The same process explains a lot of nasopharyngeal carcinoma symptoms. The cancer might cause a sense of fullness inside of the ear that can feel like a wax build-up but is in fact a build-up of fluid in the middle ear due to a blockage or obstruction. If you experience fullness or pain in only one ear that doesn't go away, it's best to have a doctor take a look at it.
