Fighting Breast Cancer with Whole Food Plant Based Weapons

Evidence of the positive impact WFPB diets have on the prevention and treatment of Breast Cancer continues to pile up.

Click here for a study that showed that vegan women had 34 percent lower rates of female-specific cancers such as breast, cervical and ovarian cancer. This was compared to a group of healthy omnivores who ate substantially less meat than the general population (two servings a week or more), as well as after controlling for non-dietary factors such as smoking, alcohol, and a family history of cancer.

The protective effect of WFPB diets is thought to be due to reduction in the levels of Insulin-like Growth Factor–1(IGF-1)

Click here for a Dr. Greger video that discusses IGF-1 and its link to cancer growth and metastases.

So, to what degree must we move towards a plant-based diet in order to reduce IGF-1 levels enough to provide a protective effect.against cancer?

The Adventist Health Study – 2 showed the thousands of American Vegans studied not only had lower rates of obesity, diabetes, and hypertension, but significantly lower cancer risk as well.

This may be explained by research done by Drs. Dean Ornish and Nobel Prize winner Elizabeth Blackburn.  They found that a vegan diet affected more than 500 genes in only three months – turning on genes that prevent disease and turning off genes that cause breast cancer, heart disease, prostate cancer, and other illnesses.

This is exciting because it’s more evidence confirming that we are not helpless victims to our genes that predispose us to chronic disease.  The best weapons we can use to keep cancer and other chronic diseases at bay are knives, forks and spoons.


  1. I am a firm believer in WFPB diets, and have been a vegetarian for almost 15 years and a vegan for slightly more than a year. Thanks in no small part to Dr. Greger’s convincing videos on the multitude of health benefits of WFPB diets. But I know at least one person, vegetarian since birth, who died of cancer in his mid-sixties. Do you agree that WFPB diets though anti-diseases, is no guarantee of good health?

    • Dominic Marro RD CDN says:

      Yes. I agree that following a WFPB diet does not guarantee a long life free of chronic disease. However, I strongly believe that WFPB diets provide us the best protection against chronic disease.
