This comprehensive review examines ten natural products that have been proven in clinical studies to help fight breast cancer. These products—including omega-3 fatty acids from fish, compounds in broccoli sprouts, garlic, soy, curcumin from turmeric, and green tea—work by triggering cancer cells to self-destruct, stopping their growth, and preventing blood vessel formation that feeds tumors. What makes these findings especially promising is that these natural products appear to work well alongside conventional treatments while causing minimal side effects, offering patients additional options for managing this serious disease.
