Dr..my 86 yr. old Mom has just been sent home to die with a Glioblastoma Brain Tumor ..Drs have explained that it is a very fast growing tumor that has already started spreading to the other side of her brain. The Tumor has effected her vision as while as her speech, however she speaks some but readily forgets. The Dr. explained at first, that this Tumor was cancerous, but because of her age would not recommend putting her through Chemo or Radiation ...Now we found out that Mom s Tumor was not cancer, but is moving quickly, and is fatal. Mom has been given 2-6 mo. I an my 8 siblings are totally confessed, can you give me a simple explanation as too why we are being told now that its not cancer? Thank you so much for your insight...Carolyn
