Pomegranate polyphenols have shown strong potential in preventing and treating breast cancer through various anti-cancer effects.
The researchers conducted a systematic review of scientific literature available on PubMed and Google Scholar, that included articles written in English over the past two decades. They focused on the original research articles examining the potential role of pomegranate and its polyphenols in breast cancer prevention and treatment. In total, they selected 28 papers for review, including both clinical and preclinical studies.
The research revealed that pomegranate polyphenols display potent anti-cancer properties through several mechanisms on breast cancer cells. These mechanisms include anti-estrogenic, anti-proliferative, anti-angiogenic, anti-inflammatory, and anti-metastatic effects. Additionally, pomegranate extracts could induce cell cycle arrest, cytotoxicity, and inhibit invasion in breast cancer cells. However, findings from two small clinical trials were contradicting. Overall, pomegranate was recognised as a promising natural strategy for managing breast cancer.

Clinical Study Breast Cancer Pomegranate
In this study, 64 healthy postmenopausal women were randomly assigned to consume 8 ounces of either 100% commercial pomegranate juice or apple juice daily for a period of 3 weeks. The aim was to observe the effect of pomegranate juice intake on the serum levels of various sex hormones and sex hormone-binding globulin.
Despite no significant alterations observed in the serum sex hormones or SHBG overall, a subgroup analysis of 38 normal weight participants indicated a significant reduction in estrone and testosterone levels for those who consumed pomegranate juice compared to the control group. The decrease was seen only in this subgroup, and not in the total group of participants. Hence, the direct effect of pomegranate juice on hormonal levels may be more apparent in normal weight postmenopausal women.
