Two newly discovered genes may act as master control switches in the progression of the most aggressive form of brain cancer, glioblastoma.Researchers say the two genes are active in about 60% of all glioblastoma patients and identifying these genes could help identify those with this type of aggressive brain tumor.Glioblastoma is among the most lethal types of brain cancer because it rapidly spreads throughout the brain and creates inoperable brain tumors. Senator Edward Kennedy died of glioblastoma only 16 months after he was diagnosed with the disease.
