- Peripheral nerve tumors are growths in or near strands of tissue (nerves) that carry signals from your brain to the rest of your body. These nerves control your muscles so you can walk, blink, swallow, pick up things, and do other activities.
Peripheral nerve tumors can occur anywhere in the body. Most of them are not cancerous (malignant) but can cause pain, nerve damage, and loss of function in the affected area. Neurofibroma Treatment in Hyderabad
symptoms
Symptoms and signs of a peripheral nerve tumor arise from direct effects on the main nerve or from pressure the tumor exerts on nearby nerves, blood vessels, or tissues. As the tumor grows, it may be more likely to cause signs and symptoms, although the size of the tumor doesn’t always determine the effects.
The signs and symptoms of peripheral nerve tumors vary depending on the location of the tumors and the tissue affected. They include:
- Swelling or lumps under the skin
- Pain, tingling, or numbness
- Weakness or loss of function in the affected area
- Dizziness or loss of balance

- It is not known why most peripheral nerve tumors develop. Some are associated with known hereditary syndromes such as neurofibromatosis (types 1 and 2) and schwannomatosis. Others can be caused by a defective gene or triggered by injury or surgery. Neurofibroma Treatment in Hyderabad
Risk factors
Peripheral nerve tumors are more common in people who:
Neurofibromatosis (types 1 and 2) and schwannomatosis. In these diseases, tumors grow on or near nerves throughout the body. These tumors, often multiple, can cause a variety of symptoms and signs depending on their location. These tumors are usually not cancerous.
A history of radiation therapy. Years later, if you’ve been exposed to radiation, there’s an increased risk of peripheral nerve tumors.
Complications
Non-cancerous and cancerous peripheral nerve tumors can compress nerves and cause complications, some of which can be permanent:
- Numbness and weakness in the affected area
- Loss of function in the affected area
- Balance disorders
- Pain
