The Sontag Foundation is the largest private funder of brain cancer research in North America. The Foundation was established in 2002 by Frederick and Susan Sontag following Susan’s successful battle with a normally lethal form of brain cancer. To date, the Foundation has granted over $50 million in funding to support brain cancer research. In 2014, the Foundation established The Brain Tumor Network, to provide free navigation services for patients with brain tumors, helping to connect them to brain cancer specialists, second opinions and clinical trials.
