BIG network = over 50 member groups covering 55+ countries

Intro text: 

With breast cancer being the most common cancer in women worldwide, global collaboration and a shared vision are necessary to fight this devastating disease efficiently.

BIG encompasses over 50 member groups worldwide, which are breast cancer focused collaborative research groups and data centres. Some BIG groups are regional, some are national or even international.

Each member group is associated with one to several hundred member hospitals and investigators, creating a global network of thousands institutions worldwide that are working together towards one goal: better treatments for breast cancer patients... and ultimately finding a cure.

BIG means... No borders. No boundaries. Only possibilities.

The power of shared knowledge

Research issues are discussed with breast cancer opinion leaders from research groups from around the world.

Each member group is represented within the BIG network by one voting and several non-voting delegates.

The final decision-making body of BIG is its General Assembly, consisting of the member groups embodied by their voting representatives.
