How common are malignant nerve sheath tumors?

How common is Malignant Peripheral Nerve Sheath Tumor? Sarcomas are rare cancers and MPNST is a rare type of sarcoma, making up 5% to 10% of sarcoma cases. MPNST is most common in young adults and middle-aged adults. MPNST is more common in people with a genetic condition called neurofibromatosis type 1 (NF1).

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 [1].

Are most nerve sheath tumors benign?

Nerve sheath tumors such as neurofibromas and schwannomas are mostly benign, but malignant nerve sheath tumors can be serious and require prompt treatment.

Can a nerve sheath tumor go away on its own?

They are very amenable to treatment, but sometimes the best option is no treatment at all. Depending on the details of your condition, leaving your benign nerve sheath tumor alone may be your best choice.
