A schwannoma (sh-won-oma) is a tumour of the tissue covering nerves, called the nerve sheath. These tumours develop from a type of cell called a Schwann cell, which gives them their name. Schwannomas are often not cancerous (benign). The commonest type of benign schwannoma is the acoustic neuroma. This can cause deafness because it grows on a nerve called the 8th cranial nerve, which controls hearing.
Treatments include surgery, radiotherapy and chemotherapy. Because these tumours are so rare, it is difficult to find information about them. One review of 54 patients with this type of nerve tumour treated over the last ten years found that the people likely to do best
Had tumours smaller than 5cm across
Were able to have their tumours completely removed
Tended to be younger rather than older
These tumours don't respond all that well to chemotherapy. This treatment may be used to try to shrink the tumour or keep it at bay, but it is unlikely to cure it. They may respond well to radiotherapy, but unfortunately, there is a limit to the amount of treatment you can have to any one part of the body. If you have too much it will damage the normal tissue in the area.
Hmmmmmm I wonder how they get the tumor out without injuring the nerve. Do you know?
