What causes acoustic neuromas?

No one is sure about what causes acoustic neuromas. In some cases, they are the result of a genetic disorder called neurofibromatosis type 2, which causes tumors on both sides of the head. Some studies have explored the relationship between acoustic neuromas and the following environmental factors: long-term exposure to loud noises, head and neck x-rays, and cell phone use. None of these factors have been proven to cause acoustic neuromas.

Doctors don't know exactly what causes acoustic neuromas. There is probably a genetic component, but there is no known cause for the vast majority of acoustic neuromas. Some sort of mutation probably causes the cells to grow at an accelerated rate. The vast majority of acoustic neuromas are sporadic and random, but a subset of these are the neurofibromatosis tumors. Doctors know that these tumors are genetic.

There is some concern that radiation and cell phones may be causing acoustic neuromas, but there's no hard and fast literature to support this assertion. However there's always a small risk. Use of either a Bluetooth wireless headpiece or a wired headpiece is therefore recommended in my opinion.
