Dr Chua graduated from Yong Loo Lin School of Medicine, National University of Singapore (NUS), and entered the highly competitive general surgery residency programme after the completion of housemanship.

Thereafter, she started practising at Sengkang General Hospital and went for formal fellowship training at the prestigious renowned Kameda Medical Centre in Japan, in minimally invasive breast surgery and oncoplastic breast surgery. Since her return, she has frequently been invited to participate as a faculty instructor to help train others in advanced breast surgery. She is also currently the programme director of the Sengkang General Hospital Advanced Breast Fellowship Programme (Minimally Invasive Breast Surgery and Oncoplastic Breast Surgery).

Dr Chua strongly believes in working closely alongside patients and other professionals in a multi-disciplinary team to create individualised treatment plans for patients, targeting key areas ranging from clinical to psycho-social aspects, for the best quality of life possible. Besides the top priority of oncological safety, she considers all aspects of patients’ needs including aesthetic cosmesis, quality of life, function and sensation. She tailors each individual patient’s needs specifically during her thorough consultations, having won many awards for her bedside manners. This is aided by her fluency in English and Mandarin, proficiency in Japanese, as well as dialects such as Cantonese and Hokkien.
