A sudden increase in earwax is not a sign of cancer. The clinical manifestations of middle ear cancer mainly include severe pain in the ear, new growths in the ear canal, and bone destruction. Repeated local pus flow and foul odor can be diagnosed through CT examination. In some patients, the earwax secretion is very strong and the cerumen glands in the ear canal are very strong, which is not a disease but a normal physiological phenomenon. 3. Other patients, such as those with fungal infections of the external ear canal, repeatedly pick at their ears and repeatedly form flakes in the external ear canal, thinking that they are manifestations of ear wax.
