About St. Jude
Research Hospital

St. Jude Children’s Research Hospital is leading the way the world understands, treats and defeats childhood cancer and other life-threatening diseases. Everything we do is centered on finding cures and saving children. And families never receive a bill from St. Jude. We pay for treatment, travel, housing or food – because all a family should worry about is helping their child live. By sharing our knowledge freely and exchanging ideas openly, we’re inspiring more collaboration between doctors and researchers worldwide, and, as a result, more lifesaving treatments for children everywhere.

At St. Jude, we won’t give up. We do everything possible to end childhood cancer and other life-threatening diseases.
