Nerve sheath tumors include schwannomas, neurofibromas and others. They grow slowly but may eventually press against the spinal cord or nerve and cause pain or loss of function.
How common are nerve sheath tumors?

Where do nerve sheath tumors grow?

Are most nerve sheath tumors benign?
A nerve sheath tumor is an abnormal growth within the cells of this covering. Nerve sheath tumors such as neurofibromas and schwannomas are mostly benign, but malignant nerve sheath tumors can be serious and require prompt treatment.
What percentage of nerve sheath tumors are benign?
Tumors of peripheral nerve are benign in at least 85–90% of clinically symptomatic cases, and likely a larger percentage of subclinical cases .
Can nerve tumors be removed?
Surgery. You may need surgery to remove a peripheral nerve tumor. The goal of surgery is to remove the entire tumor without damaging nearby healthy tissue and nerves. When that isn’t possible, surgeons remove as much of the tumor as they can.
Can tumors hurt?
Pain from cancer
The primary ways that cancer itself can cause pain include: Compression. As a tumor grows it can compress adjacent nerves and organs, resulting in pain. If a tumor spreads to the spine, it can cause pain by pressing on the nerves of the spinal cord (spinal cord compression).
Does benign tumors cause pain?
Most benign tumors are not harmful, and they are unlikely to affect other parts of the body. However, they can cause pain or other problems if they press against nerves or blood vessels or if they trigger the overproduction of hormones, as in the endocrine system.
