Doctor Elizabeth Au was awarded a Public Service Commission scholarship to study medicine at the National University of Singapore in 1981. She subsequently passed the Master of Medicine examination in Internal Medicine under a Ministry of Health scholarship, and passed the membership examination for the Royal College of Physicians in London, both in 1990. She underwent speciality training as a fellow in Medical Oncology at the renowned Mayo Clinic in USA under a Ministry of Health HMDP scholarship. Within four months of starting her fellowship, she was promoted to the position of Senior Clinical Fellow in recognition of her medical knowledge and clinical competency, a rare honour for a fellowship.
She is a member of the American Society of Clinical Oncology and the Singapore Society of Oncology and a fellow of the Academy of Medicine Singapore, and has presented and published her work in internationally renowned peer reviewed journals such as the Journal of Clinical Oncology, British Journal of Haematology, and Annals of Oncology.
She was one of the pioneers of the Department of Medical Oncology at the Singapore General Hospital and was involved in the early development of the National Cancer Centre. She developed interests in gastro-intestinal and breast oncology and eventually headed the gastrointestinal cancer team. She was principle investigator of several clinical and laboratory trials. Some of these led to registration of new chemotherapy drugs.
She was the first head of Cancer Education and Information at the National Cancer Centre leading to the formation of the first cancer information call centre in Singapore, the Cancer Helpline.
She left public service to set up the Cancer Centre at Raffles Hospital, as Consultant Medical Oncologist providing clinical service as well as training medical and para-medical personnel in oncology.
She currently practises at Mount Elizabeth Medical Centre providing consultation, treatment and counselling for all types of cancer. She works closely with surgeons and physicians to ensure a holistic treatment for every patient.
