Finding a cure for breast cancer is one of the biggest challenges faced by researchers from around the world.  


Significant progress has been made to improve both the chances of survival and the quality of life of women affected by the disease.  However, breast cancer remains the second most common cancer in the world and is still responsible for too many deaths annually.


By bringing together the top breast cancer experts from around the world to conduct innovative research, BIG has the global reach and expertise required to find a cure. We need to support such critical research to give hope to women affected by this devastating disease, and their families.
