Study reports brain tumors may arise when damaged brain tissue does not heal correctly. Researchers say some glioblastoma form when the normal healing process gets derailed by mutations. This process could begin many years before patients become symptomatic of brain cancer.
The healing process that follows a brain injury could spur tumour growth when new cells generated to replace those lost to the injury are derailed by mutations, Toronto scientists have found. A brain injury can be anything from trauma to infection or stroke.
The findings were made by an interdisciplinary team of researchers from the University of Toronto, The Hospital for Sick Children (SickKids) and the Princess Margaret Cancer Centre who are also on the pan-Canadian Stand Up To Cancer Canada Dream Team that focuses on a common brain cancer known as glioblastoma.
