Radiation Therapy

Radiation is a type of energy that travels through the air as waves. Radiation therapy uses high doses of radiation to kill cancer cells or stop them from growing.

If you are offered radiation treatment you will:

  1. Meet with a Radiation Oncologist and be asked to sign a treatment consent form
  2. Be booked for a "Radiation Planning" visit with a Radiation Therapist. At this visit you will have a CT scan which is used to design your treatment plan
  3. Be give between 1 and 40 treatments depending on your plan. They are booked daily from Monday to Friday
  4. Have a schedule printed for you on your first treatment day with all of your visits, dates and times
