Dr Paul De Ieso

Radiation Oncologist
Refer a patient

I provide a thoughtful, patient-centred Radiation Oncology service which focusses on using a strong evidence base to direct clinical decision-making. I pride myself on building strong and lasting relationships with my patients by listening to their concerns and keeping them well informed throughout the cancer journey.


Dr Paul De Ieso completed his general medical studies at the University of Adelaide in 2000 and was admitted to the Royal Australian College of Radiologists and Radiation Oncologists in 2009. He then completed the Windeyer Fellowship at Mount Vernon Cancer Centre in London, followed by an invaluable three year Fellowship at the Royal Marsden Hospital in Chelsea, London. During his time in London, Dr De Ieso fostered strong professional relationships with Medical and Radiation Oncologists that evolved into scientific publication and clinical collaboration.

Dr De Ieso commenced his Consultant Radiation Oncology career in Darwin in 2013, providing much needed Radiation Oncology services to the people of the Top End of Australia. While in this role, he provided satellite services to Alice Springs, was lead clinician for the introduction of the Northern Territory prospective prostate cancer clinical registry and was the clinical lead for the introduction of Deep Inspiration Breath Hold (DIBH) techniques for breast cancer patients needing radiation therapy.

With a number of first and co-authored cancer-related publications, involving various tumour sites, Dr De Ieso has a special interest in skin, breast, head and neck, gastrointestinal, soft tissue, and urological malignancies. He is also passionate about the use of advanced radiation therapy technologies to reduce the side effects of therapy while optimising patient outcomes.
