The incidence rate of middle ear cancer is not high. Middle ear cancer is a malignant tumor that occurs in the middle ear, mainly caused by long-term infection of the middle ear, and suppurative otitis media is one of the most important causes of middle ear cancer, with symptoms such as bleeding or bloody secretion from the ear canal, earache, hearing loss or deafness, tinnitus, difficulty in opening the mouth, paralysis of facial nerves, enlarged lymph nodes of the neck, and so on. Most middle ear cancer patients have long-term chronic otitis media history, so timely treatment of chronic purulent otitis media is an effective measure to prevent middle ear cancer. Besides, not scratching the ear when itching, not pulling out the ear frequently, and paying attention to preventing dirty water from entering the ear when bathing and washing hair are also effective measures to prevent middle ear cancer.
