My preacher at church was diagnosed with GBM. I don't know all the details, but he passed away 16 days after he found out he had the cancer. He was 73.
I want to provide information about a book that maybe helpful to those with GBM. It is called "Outsmart Your Cancer - Alternative Non-Toxic Treatments That Work". It's about a product called Protocel.
My sister-in-law's father had prostate cancer which then went into his bones. He has been taking Protocel. When I asked my sister-in-law if her dad was noticing any difference since taking it, she said oh yes. Without it he was lying around and very week. I saw him at Christmas and you could not tell he had anything wrong. He is full of life. From the little I have read about Protocel, it works best on agressive brain tumors. He buys it from a place in Ohio. If you Google Protocel, you will find the information and if you can't find it let me know and I will get you the link to where I found it. Protocel basically chokes the tumor of oxygen from what I understand. Without oxygen the tumor cannot live. There is also information on what not to eat, like sugar, which feeds the tumor and what supplements to take and not take. I pray you will all find the answer to stop this horrible cancer from growing and my best to you all.
Unfortunately, I could not get this information to my preacher's family in time to help him. We will miss him so very much. What a great man he was. He lived his life for the Lord every day. He makes me want to be a better person.
