Getting Started with Radiation Oncology

At the Radiation Oncology Department in the Cedars-Sinai Samuel Oschin Comprehensive Cancer Institute, our expert team of radiation oncologists and healthcare professionals works together to make sure you know what to expect during your treatment with us.

Your First Visit

Your first appointment will be an initial consultation to find out if radiation oncology is the appropriate treatment for your needs.

If radiation therapy is prescribed, your next visit will include a CT simulation scan of the affected area. During a CT simulation, you must be immobile. This is a scan of the cancer area that will be treated. The images are collected and sent to a physicist for planning with your radiation oncologist.

The radiation oncologist will also give the dosimetrist or medical physicist the prescription that includes how much radiation you need, the targeted area and the best type of radiation treatment to use. A physicist will use the images to prepare a treatment plan that meets the prescription determined by your radiation oncologist. The length of treatment is different for each method of treatment.

During Radiation Treatment

  • On your first day of treatment, you will be shown the machine that will be used for your radiation therapy. The radiation therapist will explain the treatment setup and process.
  • Your ongoing treatment will be delivered by a radiation therapist, and you will have weekly check-ins with your doctor.
  • On your last day of treatment, you may have a follow-up appointment with your doctor.
  • The number of treatments will depend on your type of cancer and the treatment plan designed by your physicist and doctor.
