You need to ask as many questions as you can of his doctors/specialists. My husband was diagnosed with a grade 4 glioblastoma in late March. He also had surgery with hopes of more time. However we were never given the full biopsy report and 18 days later as he was getting ready for 6 weeks daily radiation and chemo, he suffered a stroke. We were told it was caused by pressure from the tumor recurring. We were never promised and told upfront that it was like dropping seeds into soil then trying to pull up weeds, you can never get them all. We
were told there was no cure, his condition was terminal but never expected it to return so quickly. Sadly 45 days from initial diagnosis he passed. I have read there is a newly discovered treatment where the cells are frozen that has been successful but we didn't know and were never offered that. So again, ask questions. I will pray for him.
