In most cases 90% of Meningiomas are benign (non-cancerous) and do not tend to spread out to the rest of the body or nervous system. These tend to grow at a very slow rate and usually show no symptoms until the tumor gets relatively large. This is due to the gradual compression of the brain over time. Although benign
