Too much of a bad thing can be good in brain tumors

7 abril 2015

DNA mutations can cause cancer but in some cases, more mutations may mean a better prognosis for patients. A comprehensive genomic analysis of more than 700 brain tumors has revealed one such subtype of the most malignant brain tumor, called glioblastoma, or GBM. This subtype possesses thousands of tumor-specific DNA errors or mutations instead of dozens observed in most glioblastoma cases. It is also associated with longer survival.
