Radiation oncologists​

Radiation oncologists are medical doctors who specialise in treating cancer patients using radiotherapy treatment. They focus on a multidisciplinary approach to cancer management through collaboration with other cancer specialists.


Radiation oncologists are trained to prescribe the most suitable course of radiotherapy. They plan your treatment together with radiation therapists and medical physicists, to cure or reduce the symptoms of cancer. They achieve a precise treatment plan unique to each patient by combining medical and technical expertise. They have a major role in your radiotherapy treatment and aim to ensure the following:

  • Inform you of the role of radiotherapy in your cancer treatment
  • Advise you of radiation techniques most suited to you
  • Communicate your radiotherapy plan to other doctors involved in your care
  • Outline the logistics of treatment
  • Explain the potential side-effects and how to manage them
  • Provide ongoing medical care throughout your radiation course
  • Ensure your recovery is supported and followed up


All of our radiation oncologists are involved in teaching medical students as well as on-the-job training of advanced trainees. The majority also take part in clinical trials research and you may be asked if you wish to participate.
