We will find a cure for breast cancer through global research and collaboration.

Our Partners

BIG’s mission is to facilitate breast cancer research internationally by stimulating cooperation between its worldwide members. But not only.

To fight disease in the most efficient way, global collaboration between BIG and all key players in the research process is essential.





  Collaboration is key for research, and BIG is all about collaboration!

Together, BIG and NABCG strive to improve the care and cure of breast cancer patients through international collaboration.

Patients’ needs and quality of life are in the heart of BIG’s activities. BIG has built a close collaboration with Europa Donna – the European Breast Cancer Coalition – and other patient advocates to better understand patients’ needs and ensure that BIG’s work stays relevant and ethical.

BIG is extremely grateful to all its supporters – foundations, institutions and individuals – who donate funds and energy to BIG’s cause and make it possible to get closer to finding cures for breast cancer.
