A Schwannoma is a type of tumour that develops from Schwann cells responsible for producing the protective covering (myelin sheath) around nerve fibres. These tumours are usually noncancerous and can occur anywhere in the body where there are nerves. When a Schwannoma grows on a nerve, it can cause symptoms such as pain, weakness, or numbness in the affected area. Treatment typically involves surgical removal of the tumour, although in some cases, radiation therapy may be used. While Schwannomas are generally benign, their location and size can lead to complications if left untreated.
