Can Peaches Prevent Breast Cancer?

Maylin Rodriguez-Paez RN

You may really enjoy peaches in the summer, but could they also be protecting you from breast cancer?

The answer may be a resounding yes, according to the results of a new study.

Scientists at Texas A&M AgriLife Research found that peaches had the ability to prevent breast cancer cells from spreading.

This comes in light of previous research showing the cancer-killing activity of peach and plum extracts in culture.1

Peach Extracts Prevent Breast Cancer Metastasis

For this study, scientists implanted a particular aggressive strain of breast cancer cells in mice called MDA-MB-435. After several weeks, the peach extract from a strain of peaches called Rich Lady was found to inhibit the growth of tumor cells and prevent metastasis (spreading) to the lungs — and all without affecting normal cells.2

The compounds responsible for the anti-cancer effects are called polyphenols. They target enzymes called metalloproteinases, which play a role in the spreading of cancer cells.

Polyphenols are found in a variety of fruits and vegetables. They display potent antioxidant effects and prevent chronic diseases.

Eat 2–3 Peaches a Day for Breast Cancer Prevention

The results of this study are important considering that breast cancer metastasis is often more deadly than the original tumor. Additional treatments are needed to prevent breast cancer cells from spreading to the lungs, brain, and bones.

Also the results can easily be applied to people. In the study, rats were given a dose range of 0.8–1.6 mg of peach polyphenols. For humans, that translates to about two to three peaches a day, which is a reasonable amount of fruit to eat on a given day.

The study emphasizes the importance of plant-based diets for breast cancer prevention. Other research shows a diet rich in fruits and vegetables can reduce the risk of breast cancer significantly.

These, along with exercising, keeping a healthy weight, drinking sparingly, and not smoking are additional ways to prevent the disease.

The Bottom Line

Additional studies are needed to determine if peach extracts could treat breast cancer in humans, but in the meantime it can’t hurt to eat more peaches.

With breast cancer affecting about 1 in 8 women, breast cancer prevention should be a top priority for all women.

The presence of polyphenols really do hold a lot of benefits it would seem. These are one of the nearly 100 active compounds found in coffee, and there are several studies which have linked this ancient beverage to significant health benefits as well. The most recent cancer-related study found that drinking coffee regularly could help reduce a person's risk of developing liver cancer by as much as half compared to those who don't drink regularly. Whether its from peaches or coffee, polyphenols really have me intrigued as of late.

Stephen Knows Cancer - Much of the health benefits stemming from food are related to their polyphenol content. Thanks for chiming in! said...

Hi Maylin,

First off, I came across your site and wanted to say thanks for providing a great cancer resource to the community.

I thought you might find this useful infographic interesting, as it shows the detailed effects of chemotherapy in an interactive format:

Naturally, I’d be delighted if you share this embeddable graphic on , and/or share it on social. Either way, keep up the great work Maylin!
