Acoustic neuroma is a rare benign (noncancerous) tumor that arises from the sheath surrounding 'vestibulocochlear' nerve (or the eighth cranial nerve). This nerve connects the ear to the brain and helps you to hear and maintain balance of posture. It is a slow growing tumour and does not spread to other parts of the body.The exact cause of an acoustic neuroma is not understood yet. The only known risk factor for acoustic neuroma is having a parent with the rare genetic disorder “neurofibromatosis 2”. This is a rare genetic disorder that causes tumours to develop throughout the body alongwith a variety of neurological problems. According to a research, the characteristic feature of neurofibromatosis 2 is the development of benign tumours on the eighth nerve on both sides of your head and on other nerves. If you have an affected parent, there is a 50% chance of inheriting the disease though only a minority of cases with acoustic neuroma has the risk of inheritance.
Some other probable risk factors for acoustic neuroma include:
Currently there are no guidelines or known measures that help prevent the development of an acoustic neuroma.
Following a healthy lifestyle can improve your body's defenses, the immune system and reduce the general risk of illness. Regrettably, however, it does not prevent the onset of acoustic neuroma. Adopting a healthy lifestyle, healthy eating habits, regular exercises and good mental health can help in rehabilitation after treatment of the disease. If a person develops acoustic neuroma, the best opportunity for cure is appropriate diagnosis and treatment.
