The purpose of this study is to demonstrate that integration of exercise intervention into standard post-cancer directed treatment care will improve patient reported pain, decrease the need for medications to manage chronic pain and improve functional and psychosocial outcomes in survivors of cancers in children and adolescents. Our central hypothesis is that integration of exercise interventions into standard post-cancer directed treatment care will be acceptable and feasible while improving patients' pain, decreasing the cumulative dose of pain medication and improving patients' functional and psychosocial outcomes as compared to patients who only receive standard post-cancer directed treatment care.

4. CCS who have evidence in their medical record of an absolute contraindication to complete any of the physical assessments in their medical record. This exclusion criterion is at the oncologist's discretion when research staff will contact the medical oncologist via secure email or secure message through the electronic medical record for approval to approach their patients for the study and for medical clearance. The oncologists can update this information at any time during the study if there is evidence of an absolute contraindication to complete any of the physical assessments.
