@pieperfarm, you ask a good question that is often asked by cancer patients.

- Sugar's Role in Cancer https://connect.mayoclinic.org/blog/cancer-education-center/newsfeed-post/sugars-role-in-cancer-1/
According to this article by Mayo Clinic nurse educators "Sugar seems to be a major source of anxiety and fear for people with cancer. There is a myth circulating that sugar feeds cancer and that avoiding sugar will prevent the growth of cancer. To set things straight…sugar does not cause cancer on its own. Giving sugar to cancer cells does not make them grow faster and depriving cancer cells of sugar does not make them grow more slowly. ..."

Eating a heathy diet can reduce the risk of getting cancer and the risk of recurrence. Less sugar is usually part of a health diet. Sugar does not "feed" cancer.

@melcanada just posted this great video in another discussion in the Prostate Cancer support group that is worth posting here too.
