Hi. My older sister had astrosytoma stage 4 11 years ago. I regret to say she had surgery and chemo but lived only 1 year. It came back so agressive that they could not do any more. I don't want to get you down because they have come so far along with treatments so you really don't know. I also was diagnosed with astrosytoma grade 3 just last June and mine is inoperable. I have gone through 7 weeks of radiation along with 7 weeks of chemo. I now have chemo once a week for 6 months. I just had a MRI last week and I am waiting for the results. I feel good and I feel like I am beating it. I just keep thinging positve and just keep fighting it. I hope you do well and god bless.
