Accessed April 2, 2017. In that form of therapy, radiation is implanted directly into a tumour or tumour-bearing tissue. It can also be used to help kill remaining cancer cells that could still be hidden or undetected in your body. Ionizing radiation includes both electromagnetic waves and particle radiation. Intensity-modulated and image-guided radiation therapy. For example, in rare circumstances a new cancer (second primary cancer) that's different from the first one treated with radiation may develop years later. Modern radiation therapy machines produce beams that are in the high-energy megavoltage range (more than 1,000 kilovolts), which allows the beam to penetrate tissues and treat deep-seated tumours. Beams also can be positioned to enter from almost any angle and be shaped to match the characteristics of a tumor.
The radiation can come from outside of your body or be implanted.
These radiation beams start outside of the body and are directed into the body to where the cancer cells are located. In 2017, the department received accreditation through the American Society of Radiation Oncology Accreditation Program for Excellence (APEx), highlighting the department’s ongoing commitment to providing safe, high-quality radiation therapy services to its patients.

In this section, you can read about how radiation is delivered inside the breast. National Cancer Institute. The precise position of the tumour may move during a treatment session or between treatment sessions if the targeted internal organs shift during breathing or digestion. The term "radiation therapy" most often refers to external beam radiation therapy. Normal cells can often repair much of the damage caused by radiation. Charged particle beams (e.g., proton beams) are also ionizing radiation that is used in cancer treatment. External beam therapy is the most common type of radiation treatment and what most people imagine when they think of radiation therapy. Radiation therapy, also called radiation oncology, radiotherapy, or therapeutic radiology, the use of ionizing radiation (high-energy radiation that displaces electrons from atoms and molecules) to destroy cancer cells.

Ask your doctor about potential side effects, both short and long term, that may occur after your treatment. Radiation Oncology services have a long and rich history at Washington University, dating back to 1951 when the Mallinckrodt Institute of Radiology (MIR) first established a radiation therapy section, a relatively new concept in the medical community at the time.
External beam therapy (EBT). Due to the department’s early adoption of proton therapy, staff at the S. Lee Kling Center for Proton Therapy have been highly involved in the development of treatment planning and quality assurance processes for users of this machine all over the world.
Proton Therapy: The first patient treatment on the world’s first compact proton therapy system was conducted at the S. Lee Kling Center for Proton Therapy at Siteman Center in December 2013. In other cases, it may take weeks or months for your cancer to respond.
Most radiation therapy treatments use irradiation generated by linear accelerators, which impart a series of relatively small increases in energy to particles such as protons, carbon ions, or neutrons. The dose to the skin, however, is lower than with orthovoltage treatment. See our safety precautions in response to COVID-19. Check out these best-sellers and special offers on books and newsletters from Mayo Clinic. Some types of cancer are treated with small “seeds” or implants of radioactive materials directly into or next to a tumor. That causes the cancer cells to die and thus prevents their replication, thereby slowing the progression, or even causing the regression, of malignant disease. This level of control can often be beneficial for pediatric patients as it can often spare patients from receiving excess radiation to normal tissues. Radiation therapy most often uses X-rays, but protons or other types of energy also can be used. These radiations alpha (a), beta (b) and gamma (g).
A person may receive it alongside another treatment or alone. Internal Radiation Internal radiation is a less common method of giving radiation. With targeted beams of energy, radiation therapy zeroes in on cancerous cells while sparing as much healthy tissue around it as possible. After many years of growth within MIR, the Department of Radiation Oncology was formally established in 2001, and has continued to be a leader in patient care and technological innovation.
Commitment to Education: The Department of Radiation Oncology at Washington University established a training program for radiation therapy technologists in 1966. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica.
In some cases, a single treatment may be used to help relieve pain or other symptoms associated with more-advanced cancers. Early developments: Washington University was instrumental in the development of many different technologies and techniques to improve patient care, such as CT scanning, positron-emission tomography (PET), and 3-dimensional treatment planning. As you lie on a table, the linear accelerator moves around you to deliver radiation from several angles.
Radiation therapy, the use of ionizing radiation (high-energy radiation that displaces electrons from atoms and molecules) to destroy cancer cells. Image guidance can be employed to follow organ and tumour motion during treatment. All patients receiving radiation therapy will be scheduled for pre-treatment planning sessions so that the location and size of your cancer or tumor can be mapped precisely. Gamma Knife can also be used to treat some functional neurologic disorders such as epilepsy, trigeminal neuralgia, and essential tremor. Two commonly used approaches to external beam teletherapy are intensity-modulated radiation therapy (IMRT) and particle beam therapy.
Types of ionizing radiation Alpha, beta and gamma Radioactive atoms give out ionising radiations. William Powers, MD, the first director of Radiation Therapy, developed a process in which custom-built blocks made of cerrobend alloy could be used to block the delivery of radiation to areas outside of the treatment site. The Department of Radiation Oncology’s medical physics residency program, established in 1992, was the first program of its kind to be accredited by the Commission on Accreditation of Medical Physics Education Programs (CAMPEP).
In addition to being the first clinical site to use this technique to its full clinical capacity, the ViewRay MRIdian system used to deliver this type of treatment was developed by a graduate of the department’s medical physics residency program. Siteman Kids at St. Louis Children's Hospital, Barnard Health and Cancer Information Center, Program for the Elimination of Cancer Disparities, The Foundation for Barnes-Jewish Hospital, Intensity-Modulated Radiation Therapy (IMRT), Early stage cancer: radiation sometimes is the only treatment needed to shrink tumors or cause cancer cells to disappear. In addition to treating cancer, radiation oncologists may also use ionizing radiation to treat benign … Gunderson LL, et al.
Many patients only receive a single treatment using this technique, which uses a pinpoint beam of radiation to treat cancerous tissue in the brain.
