The BIG network


The Breast International Group (BIG) is a not-for-profit organisation which forms the largest international network of academic research groups dedicated to finding cures for breast cancer. For more than 15 years BIG has been conducting international clinical trials and research programmes to find better treatments against breast cancer.

Global collaboration is crucial to make significant advances in breast cancer research, reduce unnecessary duplication of efforts, share data and enable collaboration between scientists across borders, contribute to the faster development of better treatments, and increase the likelihood of cures for patients.

Today, the BIG network unites 59 groups and reaches across more than 50 countries and 6 continents, connecting thousands of hospitals and world-class breast cancer experts who collaborate on pioneering breast cancer research.

How it started.

Be part of it


Our research happens globally, and the results of our work help the thousands of women and men suffering from breast cancer locally.

BIG is different from many breast cancer charities, because we conduct our own research – we do not redistribute funding to third parties.

Our goal is to facilitate and accelerate breast cancer research and to improve treatments and quality of life for patients. Ultimately, it is about giving people more time with their loved ones.


The future is bright. Together, we will find a cure.
