Anytime you’re heading into a new facet of treatment, it helps to have some information about what to expect, including details about your consultation with the doctor, the type of therapy you may receive and where to get support so you can take care of yourself during treatment.
During your first visit to the radiation oncology clinic, you will meet with the members of your care team. Your radiation oncologist will review your history, perform a physical exam, and discuss the recommended course of treatment with you, including expected outcomes and possible side effects.
Simulation is usually done on your second visit. This is when measurements are taken to find the best way to perform your radiation treatments. Depending on the type of treatment, this may involve taking a computed tomography scan (CT scan) of the part of the body being treated, or it may involve creating special cushions to help keep your body in the same position every day while you go through radiation treatments. Sometimes our radiation therapists may draw marks on your skin or even place small, pinpoint tattoos to help make sure you are lined up exactly the same way every day for your treatment.
Treatment planning happens behind the scenes. Your radiation oncologist, a dosimetrist and a medical physicist use the measurements and images from your simulation to create your radiation plan. Their goal is to maximize the effects of the radiation on the part of your body being treated and minimize the effects on other parts of your body. Treatment planning often requires the use of specialized computers with sophisticated radiation treatment planning software. It may take several days.
After your doctor has approved your radiation treatment plan, you may need to return to the radiation oncology clinic for a verification simulation. This is essentially a final check or “dry run” to confirm your positioning on the treatment machine and other details of your radiation plan before you begin treatment.
External-beam radiation therapy is usually given in a series of outpatient visits that last 20 to 30 minutes each, five days a week (Monday through Friday). Treatment courses typically last somewhere between two and eight weeks, depending on the type of condition being treated. Your doctor will see you for a check-up at least once a week while you are going through radiation treatments.
After you have completed all your radiation treatments, you will visit your radiation oncologist to create a follow-up plan.
