In 1982, C.O.C.A., Children's Oncology Camps of America was founded by a dozen pioneer oncology camps. The personnel from these twelve camps found the lives of children with cancer were immeasurably enhanced by camping. Noting their similar experiences, these visionary souls believed a forum should be created to share their ideas and experiences. That forum known as C.O.C.A. currently consists of over 129 member camps from within the United States and Canada.

 In 1996, C.O.C.A. officially changed its name to Children's Oncology Camping Association, International, to incorporate the camps outside of the United States.

COCA meets annually at a conference hosted by a member camp. Today, COCA is known as more than a conference.  Virtual education for members is offered 5-7 months of the year, outside of the conference.
