Guide To The Symptoms Of Brain Cancer

Hearing Issues

Hearing issues, a rare category of symptoms, occur with malignant brain tumors and are more common with benign tumors in the brain. An individual who has hearing problems caused by brain cancer may frequently misunderstand what others are saying, miss parts of a conversation, ask others to repeat themselves frequently, and play music or television at an unusually high volume. Brain cancer can produce swelling in the brain due to the buildup of excess fluid and other mechanisms that can put pressure on the auditory nerve. The auditory nerve is the nerve that carries information about what an individual hears from the inner ear to the brain so it can be processed and interpreted. Brain cancer can also produce hearing issues by causing a type of hearing loss that occurs when sounds are not able to move from the outer ear into the inner ear. A cancerous brain tumor can cause the canal from the inner ear to the outer ear to become obstructed, producing hearing issues.
