The first thing anyone with cancer should do is to not eat any Sugar in any form. All cells need Sugar to grow but cancer cells really need sugar. Stay away from all forms of sugar. My brother in law died from cancer about 6 years ago, before I knew about how bad Sugar is for cancer. All he wanted to eat at the end of his life was candy.
Also Gravialo (the herb) has help a lot of people with cancer (some of them I know personaly) you can find it on line and in some health food stores. I hope this helps you and good luck.
