Three New Subtypes of Brain Cancer Were Identified at RCSI University of Medicine and Health Sciences in Dublin. They are all a type of glioblastoma.   

This discovery is vital, as these subtypes can help to identify new, effective therapies. Currently, the cause of most glioblastomas is unknown. Genetic disorders, such as neurofibromatosis and Li–Fraumeni syndrome, as well as previous radiation therapy, are potential risk factors.
