My 41 yo. Husband was first diagnosed in Sept. 2000 with an Oligodendroglia.  Re had a resection and then we did the watch and wait.  The tumor caused no recurrence until May 2008.  He again went under the knife to remove the tumor and the tumor grade stayed the same   (Grade II)  In November of 2012 the routine MRI showed and reoccurrence, and after surgery and pathology it had progressed to  an Anaplastic oligodendroglioma Grade III.  He has started chemo soon after surgery PVC and then did 6.5 weeks of radiation, which was finished in oct 2013.  Dec. 2013 MRI revealed growth.  Could it instead be Necrosis from the radiation?
