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 radiation help cancer cells?

But cancer cells grow and divide faster than most normal cells. Radiation works by making small breaks in the DNA inside cells. These breaks keep cancer cells from growing and dividing and cause them to die.

How does radiation therapy work?

Radiation therapy works by damaging the DNA of cancerous cells. This DNA damage is caused by one of two types of energy, photon or charged particle. This damage is either direct or indirect ionization of the atoms which make up the DNA chain. Indirect ionization happens as a result of the ionization of water, forming free radicals, notably hydroxyl radicals, which then damage the DNA.

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.

How do proton beams work?

Protons are particles with a positive charge. Like photon beams, proton beams can also reach tumors deep in the body. However, proton beams do not scatter radiation on their path through the body and they stop once they reach the tumor. Doctors think that proton beams might reduce the amount of normal tissue that is exposed to radiation. Clinical trials are underway to compare radiation therapy using proton beams with that using photons beams. Some cancer centers are using proton beams in radiation therapy, but the high cost and size of the machines are limiting their use.

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.

When were radioactive isotopes first used in medicine?

The use of radioactive isotopes in biology and medicine was actually started in 1901 by Henri Danlos using radium for the treatment of tuberculosis in the skin, but the application of radioisotope as tracers in biology and medicine was pioneered by George de Hevesy in the 1920s when radioactive isotopes were used naturally. In the next development they used synthetic radioactive isotopes. So that in 1943 George Hevesy was awarded the Nobel Prize in Chemistry. The first radioisotope used extensively in nuclear medicine is I-131, which was discovered by Glenn Seaborg in 1937.

What is radiation in science?

Radiation is an expenditure and energy propagation through space or a substance in the form of waves or particles. The radiation particles are composed of atoms or sub-atoms which have a moving mass and also spreads at high speeds using kinetic energy. Some examples of radiation particles are electrons, beta, alpha, photons and neutrons.

What are the two types of radioactive isotopes?

Based on the source, natural radioactive isotopes can be broadly divided into two types. The first is primordial radioactive isotopes, which exist in the earth’s crust since the formation of the universe, and the second is the cosmogenic radioisotope which is the result from the interaction between cosmic radiation and air. In addition to these two types, there are also radioactive isotopes that arise because of spontaneous decay of nuclides that can be split or due to the neutron catch nuclear reaction of cosmic radiation, and there are also extinct radioactive isotopes that are no longer present due to short half life, but because of the very small quantity it can be ignored.

What is the name of the radioactive isotopes that Seaborg discovered?

Followed by its use for the treatment of hyperthyroidism in 1940. The next discovery of the Seaborg radioactive isotopes Tc-99m and Co-60, which is a milestone in the field of Nuclear Medicine. Thanks to his services, Seaborg was awarded the Nobel Prize for Chemistry in 1951.

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.

What is internal radiation?

Internal radiation therapies use a radioactive source in or near the cancer site. Three common types of internal radiation therapy include: 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.

What is IGRT in 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.

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.

How does 3D radiation work?

These can be used to treat many types of cancer: 3D conformal radiation therapy (3DCRT) uses three-dimensional scans to determine the exact shape and size of the tumor.
