Resveratrol is a naturally occurring polyphenol in certain foods like grapes, berries, peanuts, and red wine. Resveratrol has amazing antioxidant and anti-inflammatory properties. It has been studied for its potential health benefits, including its possible role in cancer prevention and overall longevity. However, the role of resveratrol in breast cancer is more complex, with differing perspectives emerging from current research.

The Potential Benefits of Resveratrol in Breast Cancer
Some studies suggest that resveratrol may have anti-cancer properties. It can help in several ways;
- Inhibits cancer cell growth: Resveratrol actively suppresses the proliferation of certain cancer cells, including breast cancer cells, by disrupting their ability to replicate and grow.
- Induces apoptosis: Resveratrol triggers apoptosis—a self-destruct mechanism in damaged cells—in several cancer cell lines, potentially aiding in the elimination of cancerous cells.
- Reduces inflammation: Resveratrol lowers inflammation, a key factor often associated with cancer development and progression.
Contradictions About Resveratrol in Breast Cancer
Despite the promising research on resveratrol, there are some concerns about its use in breast cancer, particularly in relation to hormone-dependent breast cancers (like estrogen receptor-positive or ER+ breast cancer). These concerns stem from how resveratrol interacts with estrogen receptors:
- Estrogenic activity: In some studies, resveratrol has been shown to exhibit mild estrogen-like effects in certain contexts. This means that in estrogen receptor-positive breast cancer, resveratrol could potentially stimulate the growth of cancer cells by binding to estrogen receptors in a similar manner to estrogen itself. In some studies, resveratrol has been observed to act as an estrogen agonist in certain tissues, potentially promoting tumor growth in hormone-sensitive breast cancers.
- Contradictory research: While some studies show resveratrol’s potential to suppress breast cancer cell growth, other studies suggest that it might contribute to estrogenic effects that could negatively impact hormone-sensitive breast cancers. Researchers often report mixed results, and the effect varies depending on the dose, cancer type, and other factors.
Should We Avoid Resveratrol in Breast Cancer?
Research shows mixed results on resveratrol, so it’s important to use it with caution. If you have hormone-sensitive breast cancer, like estrogen receptor-positive (ER+) cancer, be especially careful. Talk to your oncologist before taking resveratrol supplements or eating resveratrol-rich foods like red wine or grape juice. Your doctor may suggest limiting intake to avoid possible risks.
If you have non-hormone-sensitive breast cancer, like triple-negative breast cancer (TNBC), the risks may be lower. In such cases, resveratrol might offer benefits, but more research is still needed. Its effects can vary depending on the breast cancer subtype.
In some situations, it may have a neutral or positive effect.
Resveratrol in Foods vs. Supplements
It’s important to distinguish between getting resveratrol through whole foods and supplements. The amounts of resveratrol found in foods like grapes, berries, and peanuts are much lower than in supplements. Most of the concerns around resveratrol’s estrogenic effects stem from studies using high-dose resveratrol supplements. Consuming resveratrol as part of a balanced diet, rather than in high doses, is less likely to cause issues.
EndNote
While resveratrol has promising antioxidant and anti-cancer properties, its effects in breast cancer are not entirely clear, and there are potential concerns regarding its estrogenic activity, especially in hormone-sensitive breast cancers.
If you are undergoing treatment for breast cancer, especially estrogen receptor-positive breast cancer, it’s best to avoid resveratrol supplements. You may consult your doctor before including high amounts of resveratrol-rich foods in your diet. Your healthcare provider can give personalized advice based on your specific cancer type and treatment plan.
Ultimately, it’s important to focus on a well-balanced, nutrient-rich diet that supports your immune system, reduces inflammation, and complements your cancer treatment. Always consult your oncologist before adding any new supplement or dietary changes to ensure they align with your treatment goals.
