QUESTION: Can radiation therapy be used in children?ANSWER: Yes.

Young Boy and Radiation Therapy
Radiation therapy is one of the many tools used to combat cancers. Radiation treatments utilize high-energy waves such as x-rays to kill cancer cells. Radiation can be used alone or in conjunction with other treatments (e.g. systemic therapy, surgery) to cure or stabilize cancer. Like other therapies, the choice to use radiation to treat a particular cancer depends on a wide range of factors. These include, but are not limited to, the type of cancer, the physical state of the patient, the stage of the cancer, and the location of the tumor. With radiation therapy, 3D models are created of the tumor and the surrounding normal structures. Radiation therapy is focused on the tumor, and the normal tissues are avoided (like a magnifying glass focusing light).

radiation is administered to the head and neck region, the pet may become reluctant to eat or drink in which case either
hand feeding of special diet or placement of a feeding tube along with subcutaneous administration of fluids may be
necessary to prevent dehydration and malnourishment.

QUESTION:OK, I think I understand external radiation therapy. How is internal radiation therapy planned?
QUESTION: Am I going to start radiation therapy on the same day that I meet the radiation oncologist?
ANSWER: Most likely not. If your radiation oncologist recommends radiation therapy, it would probably start within days to weeks -- we will explain more, in the coming questions. In certain cancer emergencies (for example, if the tumor is near the spinal cord, or a blood vessel that is critical), we will recommend starting radiation therapy on the same day as meeting you.

QUESTION: Should I be taking vitamins during radiation therapy? Can they affect how well the radiation works?
ANSWER: You should not take certain vitamins or supplements during radiation therapy. Take medications only as a treatment for another diagnosis, for example Vitamin D if you are deficient in Vitamin D. Otherwise, there is no reason to treat something that isn’t diagnosed. Large doses of antioxidants may make radiation work less well for certain cancers

QUESTION: Can radiation therapy cause me to develop cancer?
ANSWER: It is possible, but the risk of this is very low for most patients. We estimate the risk of a cancer forming from radiation therapy to be less than 0.2% per year. Thus, if the patient has many decades to live remaining (for example, a child), the risk builds up over time. On the other hand, for an adult, the risk is exceptionally low. If a second cancer were to develop, it would be near the region that received the treatment; so, you would not be more likely to form a brain cancer if you were treated for a prostate or breast cancer.

Radiation therapy is one of the most common treatments for cancer

QUESTION: Should I be eating anything special during radiation therapy?
ANSWER: You should continue to eat a healthy diet. Sometimes, the cancer or the treatment may make eating certain types of foods difficult. Talk to your doctor for more details.

QUESTION: If I previously received radiation therapy, can I receive it again to a different part of the body? What about to the same part of the body?
ANSWER: If you previously received radiation therapy to one part of the body, you may receive it to a different part of the body. For example, a woman who had breast cancer and was treated with radiation therapy may later develop a uterine cancer and receive radiation treatments.
If a cancer comes back in the same area that was treated before, you may or may not be able to receive radiation to that same location. The body “remembers” where it received radiation, and there are limits to what the normal organs that surround the cancer can tolerate.

QUESTION: How is external radiation therapy planned?
ANSWER:For external radiation therapy to work, we first need to do a “planning session” or a “simulation.” During this session, we use a , and possibly also an MRI or PET-CT scan, to take pictures of your anatomy. We then work with a team of experts to build 3 dimensional models based on these scans. The 3 dimensional models are created based on your cancer and the normal organs that surround or are next to the cancer (which we want to avoid). The radiation beam is generated inside of a special device called a linear accelerator, or a LINAC. Part of the LINAC will rotate around you during the treatment. Hundreds of very small x-ray beams will all converge at and around the cancer.
