Many breast cancers are estrogen-dependent. Now a class of drugs called aromatase inhibitors (AI) which block the synthesis of estrogen, are being used by mainstream medical doctors to attempt to slow the growth of estrogen sensitive breast tumors. Unfortunately, as the Mayo Clinic website points out, AI drugs — which include anastrozole (Arimidex), letrozole (Femara) and exemestane (Aromasin) — come loaded with side effects including: hot flashes, severe joint pain, muscle aches, headache, fatigue, bone fractures and a potential risk of heart disease.
Here’s the good news: there appears to be a natural alternative to AIs. Researchers say they’ve found a substance that could prevent the development of hormone-dependent breast cancers and halt the growth of estrogen-driven tumors—the pomegranate fruit. Pomegranates contain phytochemicals known as ellagitannins that work much like aromatase inhibitors, according to results of a study published in the January issue of Cancer Prevention Research, a journal of the American Association for Cancer Research. And there’s little reason to think any cancer treatment derived from pomegranates would have harmful side effects, because the fruit has long been safely consumed as a food.
Shiuan Chen, Ph.D., director of the Division of Tumor Cell Biology and co-leader of the Breast Cancer Research Program at City of Hope in Duarte, California, worked with Lynn Adams, Ph.D., a research fellow at Beckman Research Institute of City of Hope and other scientists to investigate whether phytochemicals in pomegranates can suppress aromatase and thereby inhibit cancer growth. They screened and analyzed 10 ellagitannin-derived compounds in pomegranates. The results? The research team discovered these natural phytochemicals have the potential to prevent estrogen-dependent breast cancers. One particular substance found in pomegranates dubbed ‘Urolithin B’ significantly inhibited the growth of cultured breast cancer cells in the lab.
