How is radiation given?
Radiation therapy can be given in 3 ways: 1 External radiation (or external beam radiation): uses a machine that directs high-energy rays from outside the body into the tumor. It’s done during outpatient visits to a hospital or treatment center. It's usually given over many weeks and sometimes will be given twice a day for several weeks. A person receiving external radiation is not radioactive and does not have to follow special safety precautions at home. 2 Internal radiation: Internal radiation is also called brachytherapy. A radioactive source is put inside the body into or near the tumor. With some types of brachytherapy, radiation might be placed and left in the body to work. Sometimes it is placed in the body for a period of time and then removed. This is decided based on the type of cancer. Special safety precautions are needed for this type of radiation for a period of time. But it's important to know if the internal radiation is left in the body, after a while it eventually is no longer radioactive. 3 Systemic radiation: Radioactive drugs given by mouth or put into a vein are used to treat certain types of cancer. These drugs then travel throughout the body. You might have to follow special precautions at home for a period of time after these drugs are given.

How does cancer spread?
Cancer can spread from where it started to other body parts. Doctors often assume that a few cancer cells might already have spread even when they can’t be seen on imaging scans like CT scans or MRIs. In some cases, the area where the cancer most often spreads to may be treated with radiation to kill any cancer cells before they grow into tumors. For instance, people with certain kinds of lung cancer may get radiation to the head, even when there is no cancer known to be there, because their type of lung cancer often spreads to the brain. This is done to help prevent cancer from spreading to the head even before it can. Sometimes, radiation to prevent future cancer can be given at the same time that radiation is given to treat existing cancer, especially if the area the cancer might spread to is close to the tumor itself.

Types of Radiation Therapy for Brain Tumors
There are 2 main types of therapy. You may get both types. They include:
External beam radiation therapy (EBRT)
There are several types of EBRT. The goal is to target the tumor and limit damage to nearby healthy brain cells. To limit the harm, your healthcare provider may use special types of EBRT such as:
Brachytherapy
For this treatment, the radiation is placed very close to or inside the tumor. This is done during surgery. The radiation the implants give off travels a very short distance. This helps limit the effect on nearby healthy tissue.
Brain Radiation Side Effects
Generally, side effects from radiation treatment are grouped into two categories:
Radiation necrosis
Sometimes dead brain tissue forms at the site of the radiation. This is called radiation necrosis. The mass of dead brain tissue comes from both cancer cells and healthy cells. Radiation necrosis can take anywhere from months to years to develop.
Risk of future cancer
Radiation can damage the DNA in healthy cells. As a result, you have a small risk of a second brain cancer after brain radiation. This second cancer usually occurs many years later. Talk to your radiation oncologist about the risks and benefits of radiation therapy.
The Radiation Team
Treatment planning for radiation therapy includes mapping to pinpoint the exact location of the brain tumor using X-rays or other images.

Overview
Why It's Done
- More than half of all people with cancer receive radiation therapy as part of their cancer treatment. Doctors use radiation therapy to treat just about every type of cancer. Radiation therapy is also useful in treating some noncancerous (benign) tumors.
Risks
- Radiation therapy side effects depend on which part of your body is being exposed to radiation and how much radiation is used. You may experience no side effects, or you may experience several. Most side effects are temporary, can be controlled and generally disappear over time once treatment has ended. Some side effects may develop later. For example, in rare circumsta…
How You Prepare
- Before you undergo external beam radiation therapy, your health care team guides you through a planning process to ensure that radiation reaches the precise spot in your body where it's needed. Planning typically includes: 1. Radiation simulation.During simulation, your radiation therapy team works with you to find a comfortable position for you during treatment. It's imperative that you li…
What You Can Expect
- External beam radiation therapy is usually conducted using a linear accelerator — a machine that directs high-energy beams of radiation into your body. As you lie on a table, the linear accelerator moves around you to deliver radiation from several angles. The linear accelerator can be adjusted for your particular situation so that it delivers the precise dose of radiation your doctor has order…
Results
- If you're receiving radiation to a tumor, your doctor may have you undergo periodic scans after your treatment to see how your cancer has responded to radiation therapy. In some cases, your cancer may respond to treatment right away. In other cases, it may take weeks or months for your cancer to respond. Some people aren't helped by radiation therapy.
