In 1980, Nancy G. Brinker promised her dying sister, Susan, that she would do everything in her power to end breast cancer forever. That promise became the Susan G. Komen® organization, now the worlds leading nonprofit in the fight against breast cancer. To date, we’ve invested more than $2.9 billion in groundbreaking research, community health outreach, advocacy and programs in more than 60 countries. We work to support those who need help today, while tirelessly searching for tomorrow’s cures.
