i would like anyone interested in how diet and lifestyle can affect cancer cell growth to know about a book i value dearly. its called "anticancer, a new way of life", by dr david servan-schreiber. all people can relate to it, not just ones with cancer or brain cancer. i very highly recommend it to the public at large. it lists anti-cancer super foods and what to avoid in your life to discourage cancer cell proliferation.
it has been discussed tangentially on the forum, but not specifically.
unfortunately the author passed away in july 2011 after a 20 year battle with brain cancer.
