This refers to the practice of using daily images of each treatment field to confirm patient positioning and make sure the target is in the field. These daily images are compared to the images used to plan treatment. IGRT allows your doctor to make each treatment field smaller. This allows better targeting of the tumor and helps reduce damage to healthy tissue.

What is external beam radiation?

External-beam radiation therapy is the most common type of radiation therapy. It delivers radiation from a machine outside the body. It can treat large areas of the body, if needed. A machine called a linear accelerator, or linac, creates the radiation beam for x-ray or photon radiation therapy.

Radiation is normally given five days a week Monday through Friday. In some instances twice a day radiation may be recommended. In this case the two treatments are at least six hours apart. How long each individual treatment would take depends on many factors including the dose per fraction, the number of fields used to treat a target, the technology used and the energy and form of radiation.

How does radiation therapy work?

External Radiation therapy consists of using different forms of radiation including photons, protons or electrons to irradiate a tumor in the body from outside in. That is the radiation is generated by a machine which is outside of the patient’s body and would be pointed towards the tumor or cancer. Obviously this means that the radiation has to go through the normal tissues between the external source of radiation and the tumor/cancer inside the body. We use different energies of photon or electron beams, to optimize focusing the radiation on the tumor and minimize radiation to the surrounding normal tissues. Proton beam is a unique form of radiation which would only deposit radiation at a certain point in the body i.e. tumor/cancer without radiating the normal tissue between the external source and the target of radiation.

How long does it take to get definitive radiation?

stage I-III). Depending on the type of cancer, definitive radiation can take up to 9 weeks not only because the radiation dose per individual treatments (aka fractions) is usually lower but also because the total dose of radiation is higher.

Why do cancers recur?

Some of the increased risk of recurrence, the authors believe, may be due to tumor repopulation —that is, cancer cells that remain after a halt in treatment dividing at an accelerated rate. But for many cancer types included in the study, previous studies have suggested that tumor repopulation does not have a significant impact on tumor recurrence and survival.

Side effects and their severity also influence the frequency of treatment. While generalized side effects exist, different patients may respond to the same treatments quite differently. Severe side effects may warrant an altered treatment plan or additional medications to reduce side effect symptoms.

Can you receive radiation for a tumor?

The total amount of radiation the body can receive for a treated area is highly dependent on the anatomy of the specific area receiving radiation. Different tissues and organs within our body have varying sensitivity to radiation. It is important to note that advancements in radiation technology and delivery allow care providers to administer more radiation in focused areas, depending on individual patient and tumor characteristics. As a result, although people can reach the lifetime dosage limit on one area of the body , that person may still receive radiotherapy for another tumor located elsewhere.
