Many people make up your radiation care team. Your first visit will likely be with a radiation oncologist. If you end up having treatment, you will meet more providers during future visits. Some team members focus more on the treatment delivery, and you may not meet those members.
Your radiation treatment center may have other people involved in your care as well. The entire team is there to support you.
During your first visit, the radiation oncologist will review your medical history and do a physical exam. The physician will explain the role of radiation therapy for you and what you can expect during treatment. Any questions you or your loved ones have will be answered. This is often a time for the nurse to connect with the patient and their family.
Simulation is the process of mapping the treatment area. X-rays will be taken on a CT scanner designed for treatment planning. Treatment devices used to help you lie still and comfortably on the table will be made at this time. Your skin or the treatment devices will be marked with marker or ink dots (sometimes called tattoos) that will serve as a guide for your radiation treatments. More tests may be needed to make sure the radiation will affect cancer cells but limit the effects on normal tissue. This appointment usually lasts 45-60 minutes.
Your set-up visit usually takes place in the treatment room where you will get your treatment. The radiation therapists will take x-rays or cone-beam CTs of the treatment areas to make sure that you are positioned correctly, making any changes needed. They will also check that the treatment to be delivered exactly matches the plan made by the radiation oncologist. Your first treatment will take place on the same day or the following day.
While it seems like a lot of time to plan and set up, the treatment must be given as it was planned to avoid side effects caused by radiation to healthy tissue and to get the correct amount of radiation to the treatment area.
Once the initial set-up is done, daily treatments normally follow. Treatments are often given once a day, Monday through Friday, for a number of weeks. Each treatment takes about 15 to 30 minutes, allowing time to set up equipment and get you in the correct position. However, you should plan to be there for an hour each day.
Treatments are often given each day, but some treatments are done using another schedule. These include treatment twice a day or a short course of radiation, which could be a single treatment or many treatments. This article describes external beam radiation therapy.
