Classification The World Health Organization, a specialized agency that classifies abnormal tumors affecting the central nervous system and assesses potential risk to life, has difficulty in assigning a proper grade for<unk> . The organization’s most recent grade in 2007 assigned<unk>  as a high-grade III and grade IV neoplasm, signifying that the glial tumor is dangerous for patients, causing fatal problems even after surgery. However, recent data compilation from 2011, one that compiled nearly 30 years of clinical information, confirms opposite results from patients: a 95% survival rate exists after<unk>  is completely removed (gross total resection). The most important factor for any patient when cancer is concerned – the likelihood of surviving – is still controversial for<unk> , but recent advances in the last decade have improved prognosis.
