The American Childhood Cancer Organization (ACCO) is a non-profit charitable institution that focuses on providing support to families of children diagnosed with cancer. The organization is also involved in funding research projects that target the prevention of the disease.

The ACCO was established in 1970 by parents of children who had survived cancer. Based in Washington, D.C., the organization’s initial focus was to create awareness in the government and to lobby for more resources to fund research programs on the prevention of cancer in children.

Today the organization has over 150,000 members nationwide composed primarily of children with cancer, their families, survivors of childhood cancer, and educators.  Together with their members, the ACCO is actively providing free materials to the families of children with cancer on the treatment and these effects.  In addition to providing free books, the ACCO operates a national help line to assist in referring these families to local similar organizations.
