Pediatric oncologists and radiation oncologists at Rush University Children鈥檚 Hospital understand that treating children who have cancer with radiation is different from treating adults with radiation. They are dedicated to finding the most effective treatments to fight your child鈥檚 cancer, while also minimizing side effects from radiation.

What is radiation therapy for children?
Radiation therapy uses various types of strong energy 鈥 X-rays, gamma, electron or proton waves 鈥 to damage cancer cells in children, preventing them from dividing and spreading.
Radiation therapy can also harm nearby healthy cells, which may cause side effects and interfere with a child鈥檚 growth and development. Thanks to technological advances, more precise approaches to radiation therapy are now available that specifically target cancer cells, leaving healthy tissue alone. That means radiation therapy can now provide better treatment results and fewer short- and long-term effects on children.
When is radiation therapy used for children?
Children may receive radiation therapy as a treatment for many types of childhood cancers, including the following:
- Brain and spinal cord tumors
- Leukemia
- Lymphoma
- Head and neck cancers
- Wilms tumors
- Bone cancer, such as osteosarcoma and Ewing sarcoma
- Neuroblastoma
- Rhabdomyosarcoma
- Retinoblastoma
Types of radiation therapy
There are three types of radiation. The type used depends on the type of cancer, your child鈥檚 age and other considerations. Your child鈥檚 radiation oncologist will talk to you about which of these will work best for your child.
External radiation
Most children with cancer receive external radiation. Using high-powered radiation machines guided by computer mapping, your child鈥檚 pediatric radiation-oncology team is able to deliver very precise doses of radiation to cancerous tumors or cells.
External radiation is typically provided to children on an outpatient basis. Your child will lie down, and a linear accelerator machine will aim radiation at the cancer. The machine does not touch your child. It only moves around your child鈥檚 body.
The number and frequency of radiation sessions will depend on a child鈥檚 treatment plan. You can stay with your child while the radiation technicians sets up the equipment for your child鈥檚 treatment, but you will need to leave the room for a brief period when the radiation is being given.
Your child may need to be sedated for radiation treatment, depending on your child鈥檚 age and personality. Child life specialists and clinical psychologists collaborate with your child鈥檚 care team to help ease your child鈥檚 anxieties and prepare for their treatment.
Specific types of external radiation available at Rush University Children鈥檚 Hospital include the following:
- Image-guided radiation therapy (IGRT): Using your child鈥檚 CT and other imaging scans, pediatric radiation oncologists can tailor and guide radiation beams to precisely hit cancerous cells, based on your child鈥檚 size and the size and shape of the tumor.
- Stereotactic radiosurgery: The term 鈥渞adiosurgery鈥 does not involve any surgery. Instead, pediatric radiation oncologists use the TrueBeam STx system to deliver a single, high dose of radiation to a child鈥檚 tumor, minimizing the potential for damage or side effects. This approach typically only requires one radiation therapy visit.
- Proton beam radiation therapy: Radiation oncologists at Rush are able to provide proton beam radiation therapy when indicated and recommended for their cancer treatment. Sometimes protons are good at killing targeted cancer cells without harming surrounding cells and tissue. Special machines, called synchrotrons and cyclotrons, are needed to provide this type of radiation therapy.
- Intraoperative radiation therapy: Pediatric surgeons and pediatric radiation therapists work together to deliver radiation to a tumor during surgery, particularly if the surgeon cannot remove all of the tumor.
Internal radiation
Also known as brachytherapy, internal radiation involves putting a small implant inside your child鈥檚 body, which then delivers radiation to the cancerous cells. Certain types of childhood cancer, including head and neck cancer, may benefit from internal radiation.
The radioactive implant is typically placed via a thin tube during a minor surgical procedure. Your child will be sedated or medicine will be applied to the skin to prevent any pain during the procedure. The length of time that the implant is kept inside your child鈥檚 body will depend on your child鈥檚 personalized treatment plan.
Systemic radiation
In some cases, children are given radioactive drugs via an IV or by mouth. These drugs are specially designed to find and attach themselves to cancerous cells 鈥 and then deliver a dose of radiation.
Children typically stay in the hospital for a few days while taking radioactive drugs. This is the only type of radiation that can potentially spread to other people. It wears off a few days after your child finishes taking the drugs. However, parents and other loved ones will need to take precautions 鈥 such as using separate utensils when eating 鈥 for a short time to prevent getting exposed.
Follow-up care
Your child will need regular check-ups even after completing treatment. This way, your child鈥檚 care team can monitor your child鈥檚 health. Monitoring includes making sure that the cancer has not returned, and checking for any side effects caused by treatment.
At Rush鈥檚 long-term follow-up clinic, your child鈥檚 care team will include an oncologist, nurse educator and psychologist. They work closely with your child鈥檚 primary care clinician to monitor your child for possible late effects of radiation therapy.
