About BIG

Our Vision

We will find a cure for breast cancer

through global research and collaboration


The Breast International Group (BIG) is an international not-for-profit organisation for academic breast cancer research groups from around the world.

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


How we make it happen

BIG’s mission is to facilitate and accelerate breast cancer research internationally


           The BIG network today        



BIG facilitates and accelerates breast cancer research at the international level by stimulating cooperation between its 56 member groups and other academic networks, and collaborating with, but working independently from, the pharmaceutical industry.

Linked to over 3.000 hospitals, BIG is the largest international network dedicated solely to breast cancer. Working together towards one goal: to cure breast cancer!
