Children's Oncology Services, Inc. believes that a diagnosis of cancer should not prevent a child from experiencing the simple joys of childhood.

A lot of tough challenges come along with being a young cancer patient. Friends, school and sports are often replaced by doctor visits, sick days and chemotherapy treatments.
