I think its well known that a poor diet can increase the risk of cancer. But I think its important not to give false hope that a good diet can cure or have a better effect than treatments like chemo. It is of course well known how destructive chemo is. There is a balance in these treatments and a tipping point that the side effects are much worse than the cancer . To all suffering with cancer ...... I wish you all the very best and wish you all to get well. New procedures, much more targeted are becoming available.
