Interesting City of Hope Research on Blueberries and Triple Negative Breast Cancer

Searching around for hopeful things for breast cancer patients is one of my favorite things to do (call me crazy but I like to help) and today I found some interesting research from City of Hope, a cancer center in Duarte, California.

The research demonstrated that blueberries have the ability to control tumor growth, decrease metastasis and induce cell death in triple negative breast cancer (TNBC)

A Quick Explanation of Triple Negative Breast Cancer

Triple negative breast cancer is a particular subtype of breast cancer that lacks estrogen, progesterone and human epidermal growth factor 2 (HER2) receptors and because most breast cancer tumors do have at least one of these receptors, doctors are able to target them with specific therapies.

I have spoken to quite a few patients whose tumors were triple negative and many were more than a little anxious over their diagnosis particularly because there seems to be a lot of really negative information on the Internet about triple negative breast cancer – that it accounts for only about 15% of breast cancer and that it has a poorer prognosis compared to other subtypes with the receptors present. Thus, whenever I do find some positive research about TNBC, I like to share it.

Blueberries Are a Triple Threat

Dr Shiuan Chen, director of City of Hope’s Division of Tumor Cell Biology said “blueberries help fight triple-negative breast cancers by suppressing pathways critical to tumor development and migration.” 

The research has not been carried out on real, live people yet (they are still waiting for the results of that study) but they have used it on TNBC cell cultures and also on laboratory animals with great results.  The researchers discovered that the group that received the blueberries had a tumor weight that was 70% lighter, exhibited significantly lower proliferation rates, and higher apoptosis activity (apoptosis means programmed cell death) than the group not receiving the blueberries.  So they considered that to be a triple threat against TNBC.  I found a YouTube video where they discuss their findings – click here to view it.

Researchers estimated that in humans, a person weighing 130 lbs would need 4 oz daily to achieve the good effects that the studies exhibited.

Got TNBC?  Get those blueberries in ya!

    1. Hi Valerie, thanks for your comment. You are welcome for the article, I do my best to post the information that will help the most. You might like to sign up for my free newsletters, they are full of my very best information on healing from breast cancer, some of which is not on this site.
      Loved hearing from you!

  2. Marnie,

    Thanks so much for your information. So much of what you initially hear about TNBC is scary. However, I think it is changing my life in ways that are healthy. When I was diagnosed with TNBC I immediately changed my diet. It is amazing how easy it was and how much better I feel. The right information and encouragement will go a long way in helping me to heal.


    1. Dear Mary,
      Thanks so much for your comment. You are correct about the initial diagnosis of TNBC being a scare-fest. I’ve heard some really negative things being said by doctors, but it’s only because they don’t know how much we can do to help ourselves heal from this form of breast cancer. I’m glad to hear you’ve made a start with your diet, that’s excellent. I hope that you have signed up for my free newsletters and e-books? They are full of my best information on healing from breast cancer and preventing recurrences.
      Warmest wishes,
