How does radiation therapy work?
Radiation works with the atoms and molecules in your body cells to produce electrically charged particles. Radiation therapy destroys cells directly or by interfering with cell reproduction. Normal cells are able to recover from radiation damage better than cancer cells
How is the treatment planned and delivered?
Radiation treatment is planned using a CT simulator or a simulator to determine the area for treatment. For some patients, an MR simulator is also used to help plan the treatment. The treatment is then delivered using a linear accelerator. Please refer to the booklet entitled Your Radiation Therapy at PMH for more detailed information.
Is radiation treatment painful or dangerous?
Receiving radiation treatment is like having an x-ray taken. There is no pain or sensation involved and you do not become or remain radioactive.
In response to the media reports about radiation safety, the American Society for Radiation Oncology (ASTRO) has put together a list of questions patients may want to ask their radiation oncologists about safety. Please click here for a list of questions to ask your oncologist.
Note: The ABR Medical Physicist certification only applies to Americans.
What are the side effects of treatment?
The side effects of treatment depend on many factors, such as the part of the body being treated, the type of radiation being used, the amount of radiation given and a person’s general health. You will be given specific information on what side effects you should expect by your doctor and health care team.
How long does each treatment take?
You will be in the treatment room for about 15 minutes in total, but the radiation beam is only on for a few minutes. Most of the time is spent checking and confirming all aspects of your treatment plan.
How do I find out about the PMH Lodge?
The PMH Lodge offers accommodation for patients living outside of the Greater Toronto Area. You can contact them at (416) 413-7402 or go to their web site
What happens when the treatment is completed?
After you have finished your course of treatment, your radiation oncologist or referring doctor will examine you at regular intervals. These check-ups are an important part of your care as they monitor the effectiveness of treatment and your progress.
