FAQs About Acoustic Neuroma

If you are considering Phoenix acoustic neuroma treatment, you might have a few answers. The professionals at Phoenix CyberKnife and Radiation Oncology Center is here to help put your mind at ease and answer your questions. Here are some common questions regarding acoustic neuroma

What Is Acoustic Neuroma?

An acoustic neuroma is a growth or tumor, also known as a vestibular schwannoma, that develops on the main nerve, known as the eighth cranial nerve that connects the inner ear and the brain.

Is Acoustic Neuroma Hereditary?

In most cases, acoustic neuroma appears in individuals spontaneously with no indication of history in the family 95 percent of the time. The bilateral acoustic neuroma may be referred to as hereditary. A condition known as Neurofibromatosis Type 2, or NF2, could lead to acoustic neuroma development, and this condition can be hereditary. However, those with a family history of acoustic neuromas are not necessarily at a higher risk of developing one.

How Common Are Acoustic Neuromas?

Recent studies are confirming approximately 3.5 acoustic neuromas diagnosed for every 100,000 people. In the U.S., about 5,000 cases of acoustic neuroma are diagnosed each year. Research indicates that acoustic neuroma incidents appear to be on the rise, which may be because of the advancements in MRI technology. The neuroma may be identified through an incidental scan or in one of a patient who has symptoms.

Causes of Acoustic Neuromas?

It is difficult to identify the exact cause, but some studies are starting to find certain relationships. Some ideas include

  • Defect in tumor suppressor genes
  • Regular exposure to loud noises
  • Prior head or neck radiation
  • Regular use of cell phones

It is difficult to say exactly what leads to the development of an acoustic neuroma. Research will need to continue on the subject.
