Early and late effects of radiation therapy The most common early side effects are fatigue (feeling tired) and skin changes. Other early side effects usually are related to the area being treated, such as hair loss and mouth problems when radiation treatment is given to this area.
How long are you radioactive after brachytherapy?
No radiation remains in your body after temporary brachytherapy, so there is no risk to others. Some LDR, PDR and HDR treatments require one or more days in the hospital and may cause discomfort. This may be due to the catheters or applicators and having to stay relatively still for a prolonged period.

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.

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 different types of radiation therapy?
Three common types of internal radiation therapy include: 1 Brachytherapy involves radioactive material that is implanted in the body. Dozens of tiny “seeds” containing radioactive iodine are placed at the tumor site with a special needle or catheter. This is done as an outpatient procedure. Brachytherapy is used for treatment of prostate, cervical, endometrial, vaginal and breast cancers. 2 Intraoperative radiation therapy (IORT) is used to treat an exposed tumor during cancer surgery. IORT delivers a high dose of radiation to a surgically exposed treatment area. Surrounding healthy organs and tissues are protected by lead shields. This type of radiation can be used for certain gastrointestinal cancers and other cancers that are challenging to remove during surgery. 3 Stereotactic radiosurgery (SRS) is not actually surgery. Instead, it uses dozens of tiny radiation beams to treat tumors in the head and neck with a single radiation dose. MD Anderson uses the Gamma Knife® SRS system. Gamma Knife is used to treat cancer that has spread to the brain or head or neck area, as well as tumors in the base of the skull, malignant gliomas, acoustic neuromas, pituitary tumors and meningiomas.
How is radiation delivered to cancer?
External beam radiation therapies are delivered through a specialized machine directly to the cancer site. These include the following types of radiation therapy: Proton therapy uses a beam of protons to deliver radiation directly to the tumor. A proton beam conforms to the shape and depth of a tumor while sparing healthy tissues and organs.
What is IGRT in cancer?
Several cancer types have seen improved outcomes from this including brain cancer, head and neck cancer, liver cancer, lung cancer and prostate cancer. Image guided radiation therapy (IGRT) tracks the tumor or implanted markers during radiation. This type of radiation treats tumors in areas of the body that move.
What is brachytherapy used for?
Brachytherapy is used for treatment of prostate, cervical, endometrial, vaginal and breast cancers. Intraoperative radiation therapy (IORT) is used to treat an exposed tumor during cancer surgery. IORT delivers a high dose of radiation to a surgically exposed treatment area. Surrounding healthy organs and tissues are protected by lead shields.
What causes cancer cells to stop multiplying?

What is brachytherapy in cancer?
Internal Radiation Therapy (Brachytherapy) Brachytherapy involves placing radiation sources as close as possible to the tumor site. Sometimes, they may be inserted directly into the tumor. The radioactive sources or isotopes are in the form of wires, seeds (or molds), or rods. This technique is particularly effective in treating cancers ...
How does stereotactic radiation work?
Stereotactic radiation therapy involves focusing the radiation beam on a small area and delivering very high doses. The therapy targets a tumor from many different directions so the beams of radiation converge on the tumor. This way, the ideal amount of radiation needed to destroy tumor cells is delivered directly to the tumor growth, ...
What is external beam radiation?
External beam radiation therapy is radiation delivered from a distant source, from outside the body and directed at the patient's cancer site. Systems which produce different types of radiation for external beam therapy include orthovoltage x-ray machines, Cobalt-60 machines, linear accelerators, proton beam machines, and neutron beam machines. A radiation oncologist makes decisions regarding the type of system that is best suited to treat a specific cancer patient. External beam therapy is the radiation therapy treatment option used for most cancer patients. It is used to treat many types of tumors including cancers of the head and neck area, breast, lung, colon, and prostate.
What is intraluminal radiation?
Intraluminal radiation therapy deliver s radiation to hollow organs. For example, a surgeon or a radiation oncologist inserts a specially designed tube or applicator into the lumen, or opening, of the esophagus to treat cancer. Finally, radioactive particles can be attached to small molecules and given intravenously.
How many beams of radiation intersect to form a powerful tool focused on a targeted area of abnormal tissue within the
A total of 201 beams of radiation intersect to form a powerful tool focused on a targeted area of abnormal tissue within the brain. Amazingly, the gamma knife is so precise that it damages and destroys the unhealthy tissue while sparing adjacent normal, healthy tissue.
Definition
Radiation therapy describes treatments that use high-powered waves of energy to destroy the genetic materials (DNA) in cancer cells. Ionizing radiation, the same kind of radiation used in X-rays and gamma rays, is usually used in radiation therapy because it is more powerful than the nonionizing waves that are used in microwave and radio signals.
Types
The types of radiation waves used to treat cancer are usually divided into several subgroups, and each group is used to treat particular types of cancer like: 1
Process
When the time comes to have your first radiation therapy session, here's what to expect: 2
Who Does It
Radiation therapy is performed primarily in outpatient centers or ambulatory clinics by a specialized team of clinicians that can include the following: 5
Uses
Radiation therapy is generally used to treat cancer by targeting the DNA of cells that are actively dividing. Since cancer cells divide so rapidly, many of these cells are susceptible to damage from radiation at any given time.
How to Prepare
You will have a number of preliminary appointments in which measurements and scans will be taken using a CT (computed tomography) scan. Your oncology team may mark measurements or specific sites on your skin with ink or even a small tattoo.
Side Effects of Radiation Therapy
Radiation doesn't only work during individual treatment sessions. Cells that are impacted by radiation at the time of treatment can take days—or even months—to die off completely. In most cases, this cell death, as well as damage to surrounding tissues, is what causes the side effects from radiation therapy. 1
What type of radiation is used in x-rays?
Most radiation therapy machines use photon beams. Photons are also used in x-rays, but x-rays use lower doses. Photon beams can reach tumors deep in the body. As they travel through the body, photon beams scatter little bits of radiation along their path.
How to do radiation therapy?
If you decide to have external beam radiation therapy, you will be scheduled for a treatment planning session called a simulation. At this time: 1 A radiation oncologist (a doctor who specializes in using radiation to treat cancer) and radiation therapist will figure out your treatment area. You may also hear the treatment area referred to as the treatment port or treatment field. These terms refer to the places in your body that will get radiation. You will be asked to lie very still while x-rays or scans are taken. 2 The radiation therapist will tattoo or draw small dots of colored ink on your skin to mark the treatment area. These dots will be needed throughout your course of radiation therapy. The radiation therapist will use them to make sure you are in exactly the same position for every treatment. The dots are about the size of a freckle. If the dots are tattooed, they will remain on your skin for the rest of your life. Ink markings will fade over time. Be careful not to remove them and tell the radiation therapist if they fade or lose color. 3 A body mold may be made of the part of the body that is being treated. This is a plastic or plaster form that keeps you from moving during treatment. It also helps make sure that you are in exactly the same position for each treatment
What is stereotactic radiation?
Stereotactic body radiation therapy is similar to stereotactic radiosurgery, but it is used for small, isolated tumors outside the brain and spinal cord, often in the liver or lung. It may be an option when you cannot have surgery due to age, health problems, or the location of the tumor.
Why do people have side effects from radiation?
They usually happen because radiation therapy can injure healthy cells that are near the cancer cells it is destroying. Side effects depend on the part of your body being treated. It's important to keep in mind that they differ in degree from person to person.
What is the name of the doctor who treats cancer?
