What is the other name for radiation therapy?
Other names for radiation treatment are radiation therapy, radiotherapy, irradiation, or x-ray therapy. Radiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. Your cells normally grow and divide to form new cells.
What is external radiation therapy for cancer?

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.
What doctor is trained to treat cancer?
Radiation oncologist: This doctor is specially trained to treat cancer with radiation. This person oversees your radiation treatment plan. Radiation physicist: This is the person who makes sure the radiation equipment is working as it should and that it gives you the exact dose prescribed by your radiation oncologist.
What is the treatment for cancer that has returned?
To treat cancer that has returned (recurred) If a person's cancer has returned (recurred), radiation might be used to treat the cancer or to treat symptoms caused by advanced cancer. Whether radiation will be used after recurrence depends on many factors.
Why do people get radiation to their head?
This is done to help prevent cancer from spreading to the head even before it can.
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.
What are the sources of radiofrequency radiation?
The most common sources of radiofrequency radiation are wireless telecommunication devices and equipment, including cell phones, smart meters, and portable wireless devices, such as tablets and laptop computers ( 1 ). In the United States, cell phones currently operate in a frequency range of about 1.8 to 2.2 GHz ( 2 ).
What is the spectrum of electromagnetic waves?

How does brachytherapy work?
They put it inside you using a small tube called a catheter or a device known as an applicator. Brachytherapy usually treats head, neck, breast, cervix, endometrial, prostate, and eye cancers. If your doctor uses a low dose of radiation in brachytherapy, they'll remove the implant after several days. If they use a higher dose, they usually take it ...
How long does it take for radiation to go away?
If they use a higher dose, they usually take it out after 10 to 20 minutes, and you'll get two doses a day for around 2 to 5 weeks. Depending on the type and location of your cancer and the other treatments you've had, your doctor may also place an implant in your body permanently and the radiation will weaken with time.
How long does radiation treatment take?
A visit usually lasts 30 minutes to an hour, most of which is spent getting you in the correct position. The treatment itself usually takes 5 minutes or less.
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.
