MedUniMedUni Vienna at the international forefront in the study of brain Vienna at the international forefront in the study of brain tumourstumours
In In Austria around 1,700 primary brain Austria around 1,700 primary brain tumourstumours are newly diagnosed each year. The most are newly diagnosed each year. The most common form of primary brain common form of primary brain tumourtumour in adults is the in adults is the glioblastomaglioblastoma, for which a , for which a standard therapy used worldwide was able to be established in 20standard therapy used worldwide was able to be established in 2005 with the 05 with the involvement of involvement of MedUniMedUni Vienna.Vienna.
