Hello from New Zealand
I have now had GBM for 2yrs 9 months.
Most chemo tabs. are very alkaline.
Most raw vegetable foods are alkaline.
I have read that if you can make your body slightly alkaline (7.35) and stop consuming sugar - then your cancer growth will slow or stop.
Read the book "Anticancer - A New Way Of Life" by Dr David Servan-Schreiber. He also has many small movies about cancer on www.youtube.com . David survived GBM for 19 years.
You may also find "Charlotte Gerson" interesting on youtube.
You may also find these DVD's interesting:
"Forks over Knives" and
"Foodmatters" you are what you eat.
Wishing you and your Dad a long, happy and healthy future
