Malignant brain tumors in adults are fast-growing cancers with median survival rates of 15 months, even with aggressive treatment. Researchers have been searching for genetic "signatures" (characteristic groups of cancer-causing genes) that could help in defining the kind of brain tumor the patient has. They hope to be better able to predict the course of the disease and more accurately design the patient's course of treatment.
Would this discovery be more useful for a) reducing cancer risks, b) correcting/restoring cancer cells to normal, or c) destroying cancerous tissue?
