Overview
Common risk factors in the development of acoustic neuroma are neurofibromatosis type 2 and low dose radiation.
Risk Factors
The risk factors of acoustic neuroma include:
- Neurofibromatosis type 2
The known risk factor for acoustic neuroma is having a parent with the rare genetic disorder neurofibromatosis type 2. This disorder accounts for only a small number of cases. Neurofibromatosis type 2 is characterized by development of benign tumors on the VIII cranial nerve(balance nerves) on both sides of your head but it can affect other nerves too. NF2 is an autosomal dominant disorder. The mutation can be passed on by just one parent(dominant gene). Each child of an affcted parent has a 50% chance of inheriting it.
- Low-dose radiation
Childhood exposure to low-dose radiation of the head and neck may be associated with acoustic neuroma.
