Proton Radiation for the Treatment of Pediatric Bone and Non-Rhabdomyosarcoma Soft Tissue Sarcomas

• Participants will receive radiation treatments once per day, 5 days a week for a total of 4 to 6 weeks, depending on how much total dose the tumor requires. The radiation doctor will see the participant once each week to monitor and record any side effects they may have from radiation treatment.
• A special device will be made for each participant to help them hold still during the treatment. This may either be a mask or foam cradle, depending on the area to be treated.
