Re: Radiation/Chemo vs nothing
I am so sorry. God bless your family. Nothing about this is easy. The tumor 'doubling rate' for GBM is very rapid. If medicare will cover it get another MRI to check the size of the tumor again. If you are going to do something, do it now. He may respond well, and have a little extra time. This could be the time for relatives to come and visit him, watch a movie, go fishing, or whatever he likes and is able to do. Everyone needs to be upbeat and positive or he will feel like he is surrounded by vultures.
For family members, an assignment, watch "The Bucket List" and listen to what Morgan Freeman says to his family.
My son-in-law, 24, has a diffuse brainstem tumor that has 'progressed' to a more malignant cancer. He has expressed frustration many times at the depressed attitude of people around him.
I wish the best for you, your father and the rest of your family. Take care.
