Professional Statement

Dr Daniel Tan Yat Harn is a radiation oncologist currently practising at Gleneagles Hospital, Singapore. He started his career as a radiation oncologist after graduating from the National University of Singapore in 2002.

Dr Tan trained at international medical centres with a focus on neuro-oncology. This included proton therapy at the University of Pennsylvania’s Roberts Proton Therapy Centre, USA; spine radiosurgery at Princess Margaret Hospital and Sunnybrook’s Odette Cancer Centre in Toronto; and advanced radiation technologies at Tokyo Metropolitan Komagome Hospital in Japan.

Dr Tan was the national project coordinator of the International Atomic Energy ... See more [ + ]Agency’s (IAEA) initiative to train and develop specialists in Stereotactic Body Radiation Therapy (SBRT), an advanced radiation technique, in the Asia-Pacific region.

 He was the organising chairman of the inaugural Radiology Asia 2015, a regional radiology meeting held in conjunction with the Singapore Radiological Society’s 24th Annual Scientific Meeting. He has frequently been invited to lecture on these subjects at regional meetings such as the Philippines Radiation Oncology Society Annual Meeting, the Annual Scientific Congress of the Malaysian Oncological Society, the Asia-Pacific Breast Cancer Summit and the International Society of Geriatric Oncology Asia Pacific Conference.
