Dietary advice for cancer oatients

I have witnessed cancer patients improving their status by dietary change eliminating sugars and minimizing red meats and increasing consumption  of some vegetables

Currencent cancer treatments are often quite brutal.

I saw a friend being treated with chemo for a year ands she suffered terribly.

If we could explore record and refine effective diets for patients and different  cancers it would save hospitals a fortune and time and be a lot kinder on the cancer patients bodies
