Sorry to hear about your grandmother.
I had breast cancer.
I change my diet by eat mostly raw food. 80% raw foods and 20% regular foods and exercising.
I lost over 60 pounds.
Nothing is 100% but some changes might help keep cancer in remission.
I also believe in alternative therapy.
Check out books, websites or healthfood store on cancer alternatives.
If you can afford it or have good insurance, there are cancer clinics in Mexico, Calififornia etc.
That can help your grandmother.
No single food or food substances can protect you against cancer. But scientists believe that the right combination of foods in a predominantly plant-based diet may. Evidence is mounting that the minerals, vitamins and phytochemicals in plant foods interact to provide extra cancer protection. This concept is called synergy.
Here is a list of foods we at AICR get asked about most often.
Dark Green Leafy Vegetables
Grapes and Grape Juice
Whole Grains http://www.aicr.org/site/PageServer?page...
I hope this helps.
