Your peripheral nerves link your brain and spinal cord to other parts of your body. These nerves control your muscles so that you can walk, blink, swallow, pick things up and do other activities.
Several types of nerve tumors occur. Though their cause is usually unknown, some are hereditary.
Most tumors aren't cancerous (malignant), but they can lead to nerve damage and loss of muscle control. That's why it's important to see your doctor when you have any unusual lump, pain, tingling or numbness.
