Benign nerve sheath tumors come in two forms, schwannomas and neurofibromas. They are very similar and treatment considerations for both are virtually identical.

While some extremely rare nerve sheath tumors are aggressive, or malignant(cancerous), the vast majority of them are benign (noncancerous). This means they grow very slowly and don’t always pose an immediate threat to your health.

Even so, they can cause symptoms that many patients find upsetting and, if left untreated, lead to serious neurological symptoms such numbness, weakness, and loss of balance. Typical symptoms include pain, numbness and/or loss of function in the affected area.
Peripheral nerve sheath tumors (PNSTs) are a group of primary neurogenic tumors that arise from nerve sheaths outside of the central nervous system. The vast majority are benign, however, malignant transformation is seen particularly in large tumors and those associated with neurofibromatosis type 1 (NF1).
Benign nerve sheath tumors are nervous system disorders that can come in many different forms. They are very amenable to treatment, but sometimes the best option is no treatment at all.
