This is such a good question @travelgirl. I'm tagging @smness on this conversation. Sheryl is a patient educator at the Mayo Clinic in Rochester. She and her team in the Cancer Education Center help inform and educate patients, families and caregivers. She or a colleague may have some up to date research for you about foods that kill cancer.

In the meantime, you may be interested in looking at the research and publications by Richard Béliveau, PhD and Denis Gingras, PhD http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2231485/. However, their work focuses on prevention. They wrote Foods That Fight Cancer: Preventing Cancer through Diet.
