Announced by the USPS on November 9, 2026:

While childhood cancer is rare, about 15,000 American children and adolescents receive cancer diagnoses annually, and it is the leading cause of disease-related death for children post-infancy. With this semipostal, the U.S. Postal Service supports biomedical research aimed at improving survival for children and adolescents with cancer and developing safer, less toxic treatments that reduce short- and long-term side effects. Net proceeds from the surcharge on the Cure Childhood Cancers semipostal will be donated to the National Institutes of Health for childhood cancer research. Greg Breeding, an art director for USPS, designed the stamp with original artwork by Chuck Styles.
