The main risk factor is having a family history of the condition.
Symptoms of NF2 include:
- Balance problems
- Cataracts at a young age
- Changes in vision
- Coffee-colored marks on the skin
- Facial weakness
- Hearing loss
- Ringing and noises in the ears
Signs and tests:
- Brain and spinal tumors
- Hearing-related (acoustic) tumors
- Skin tumors
- Genetic testing
- Medical history
- Physical examination
Most patients need surgery to remove tumors. Tumors also can be treated with radiation .
