28.800 steps (20km) for research against metastatic breast cancer. 
Around one in every eight women will develop breast cancer in their lifetime*. A percentage of them will be affected by an advanced form of the disease – metastatic breast cancer.

Despite the enormous progress already made in early-stage breast cancer, metastatic breast cancer is still an incurable disease that affects many people. And while some live longer than others with the disease, we still don't understand why.

The Metastatic breast cancer GPS - AURORA aims to improve our understanding of this disease, to identify genetic breakdowns, and to map the routes that cancer cells take to invade other organs. By better understanding metastatic breast cancer, we’ll be able to develop treatments to stop these cells from developing and spreading.

It costs 28.800€ for one patient to participate in the Metastatic Breast Cancer GPS – AURORA program for up to 10 years. This is why 28.800 is such an important number for us.

By taking on the Brussels 20km challenge with BIG against breast cancer and having your friends, family and colleagues sponsor your run*, you’re helping BIG’s researchers to advance important work against metastatic breast cancer. Today’s research leads to tomorrow’s cures.
(* Donations greater than or equal to 40 € per year are eligible for tax deductions)
