Me(cid:374)i(cid:374)gio(cid:373)a"s: tumours that grow between the meninges, the three membranes that cover the central nervous system, 20% of tumours found in the human brain, all meningio(cid:373)a(cid:859)s are encapsulated tumours. Aside fro(cid:373) (cid:373)e(cid:374)i(cid:374)gio(cid:373)a(cid:859)s, (cid:373)ost brain tumours are infiltrating. Infiltrating tumours: those that grow diffusely through surrounding tissue, as a result, they are usually malignant tumours it is difficult to remove or destroy them completely and any cancerous tissue that remains after surgery continues to grow. Gliomas brain tumors that develop from glial cells, are infiltrating, rapidly growing, and unfortunately common. About 10% of brain tumours do not originate in the brain.
