I am sorry about your wife...
tell her to eat at least 10 almonds a day for starters and here is the not so good part...
She must eat daily at least 5-10 APRICOT kernels and the apricot of course.
The sad part of this is that the kernels are extremely bitter but it's a cancer killer.
Dont worry about the amygdaline and the cyanide because in its natural form is chemically inactive.Apricot kernels are full of B-17 vitamin which is cancer killer.The enjyme that can release the cyanide is beta glucosidase and makes it deadly.The place in our body that "beta glucosidase" is met is in the cancer cells.So it focused only in cancer cells and kills them..But there is also another substance that is called rodanase that protects all other cells of our body from the cyanide except the ones with the cancer,thus its safe.Of course she should eat fresh fruits ,plenty of onions and garlic,fresh salades,carots and keep in mind that most of her food must be uncooked(vegetables) and fresh
Cut of sugar completely for a while...at least until she gets better.No potatoes,no alcohol.
I hope you will consider the above and wish you and your wife the best
