TWELVE years? A friend of mine died from glioblastoma. From diagnoses to death in only two weeks. He worked for UPS and one day was acting confused, two weeks later he was dead leaving a wife and kid.
Wow. Scary. Was he lucid during those two weeks?
“TWELVE years”
What is your point?
Those are fast growing very aggressive cancers
My wife was diagnosed with massive glioblastoma tumor last June. She was similar. Forget some passwords, within a week pretty much lost the ability to speak amd huge memory loss. She was in the last stages. Surgery, 30 doses of radiation, 72 doses of Temodar, and taking fenbendazole, she will be cancer free for 1 year in October.
Not all brain cancers are glioblastoma. They are the worst. My loved one had surgery two days after glioblastoma diagnosis. That and radiation gave her 8 months of life. I still miss her.
My husband collapsed at home unexpectedly. Tests in the ER showed he had an inoperable Stage 4 GBM. He died 15 days later. He had no symptoms before he collapsed. Similar scenario to your friend.
