St. Louis

At Blood Cancer United's Light The Night we gather as a community to celebrate, honor, and remember those touched by blood cancer. Companies, community partners, friends, families, and sponsors join together to instill hope and bring light to the darkness of cancer. The dollars raised by this community fund life-saving blood cancer research around the world, provide free information and support services, and help advocate for access to quality, affordable, coordinated care for patients and their families.

We are united to end blood cancer and we have a bold goal. By 2040, Blood Cancer United, formerly The Leukemia & Lymphoma Society, will enable people with blood cancer to gain more than one million years of life. This means more birthdays, more graduations, more cherished moments and memories with family and friends.

Everyone with blood cancer deserves a longer, better life. Join this powerful community at a Light The Night event near you and help us create more memories for patients and their families. Together, we Light The Night.
