One Mission is a pediatric cancer charity that does whatever it takes for kids fighting cancer and their families. One Mission programs make living in the hospital less lonely and stressful, bring back happiness in a time of fear and uncertainty, and give kids and their loved ones the support they need to get through the emotional and financial challenges of treatment. All of the programs we fund directly benefit children and adolescents diagnosed with cancer and their families. One Mission is a Section 501(c) (3) public charity under the Internal Revenue Code. All donations made to One Mission are tax-deductible to the extent allowed by the Internal Revenue Code.
