I just saw your situation on the BBC. Suggest you look into supplementing with either rubidium chloride or cesium chloride (not radio active). These salts are known to pass through the blood brain barrier and gather specifically in brain cancer tissue. They raise the pH value and kill cancer cells in the process. There are a number of sites which discuss this so google will help you. Also consider a mixture of baking soda with maple syrup cooked together. Similar principle of raising pH. Again google will give you more info. Also suggest drinking high pH (8+) water and eating diet of 66% alkaline 33% acidic food balance. Also consider cutting out all animal products except wild fish(not shellfish). Also cook only with olive or coconut oil. Good luck and may God send you a speedy and full recovery.
