New research from UCLA Health Jonsson Comprehensive Cancer Center has uncovered an exciting potential use for Mānuka honey: helping to prevent and treat breast cancer, specifically estrogen receptor (ER)-positive breast cancer—the most common type, making up 70–80% of cases.
Promising Findings from the Study
In preclinical trials, researchers found that Mānuka honey:
✅ Reduced tumor growth by 84% in mice with ER-positive breast cancer.
✅ Targeted cancer cells without harming normal breast cells.
✅ Blocked key cancer pathways that contribute to tumor growth.
✅ Enhanced the effects of tamoxifen, a common breast cancer treatment.
Why This Matters
Breast cancer remains the leading cause of cancer-related deaths in women worldwide, and resistance to traditional treatments is a major challenge. Mānuka honey’s rich composition—packed with flavonoids, antioxidants, and essential nutrients—shows potential in disrupting cancer cell growth while being a natural, less toxic alternative.
This groundbreaking research opens the door for further studies on how Mānuka honey could be used as a complementary or standalone treatment for hormone-sensitive breast cancer.
