Studies showing cancer risk with vegan diet
Posted by tinako on December 5, 2009
As an aside to my China Study postings, I’m going to pop into this posting any scientific studies I find over time that look into differences in cancer rates on a vegan diet. I promise I will include any I find that show veganism increases cancer. I am not going to include any studies that only look at vegetarians or do not differentiate between vegetarians and vegans, because a vegetarian diet is not good enough. Linda McCartney makes a good example of this. This publication makes the point that lumping “vegetarians” together may not be yielding helpful analysis. Unfortunately, most of the big studies in the U.S. don’t seem to have figured out this important difference, and so their results are not always conclusive. I think this refusal to even consider dairy as a possible bad-guy is the single biggest impediment to seeing the dramatic difference that animal products make in our health. The logic goes like this: somebody switches from meat to dairy and their health doesn’t improve; therefore don’t bother giving up meat.
Studies showing cancer risk with vegan diet:
- “Cancer and the vegetarian diet” (this article includes many graphs and sources. He uses the word vegetarian but many of the studies look at total animal product intake, as opposed to subjects who just “don’t eat meat”)
- “Vegan diet and breast cancer risk“
- “Vegan proteins may reduce risk of cancer, obesity, and cardiovascular disease by promoting increased glucagon activity”
- Dietary intervention strategies to modulate prostate cancer risk and prognosis.
- Diet and survival after prostate cancer diagnosis.
- Vegetarian diet: panacea for modern lifestyle diseases?
- Influence of the diet on cell proliferation in the large bowel and the rectum. Does a strict vegetarian diet reduct the risk of intestinal cancer?
- China-Cornell-Oxford Project
- This link is a blog, not a published, peer-reviewed study, but I welcome comments that question The China Study. I’m vegan for other reasons; if The China Study skews the truth, then out with it: “A Closer Look at the China Study.” I have not yet come across criticism of the rat studies.
Vegans who get cancer:
( I looked into Kris Carr of Crazy Sexy Cancer and she was not vegan before she was diagnosed.)
- Bif Naked, Canadian raw vegan 10 years before diagnosed with breast cancer 2008 (thanks, Janet)
- 11/12/10 – relative of a friend, vegan 10 years, developed adenocarcinoma cancer in mouth, rare and has no risk factors

People who get cancer, then switch to a vegan diet and their cancer keeps growing:
