Services and Special Interests

Oncoplastic surgery of the breast is an innovative approach to breast cancer treatment.  Deriving from the Greek language; Onco (a tumour) and Plastic (to mould), this modern discipline applies surgical techniques to reshape or reconstruct the breast after breast cancer treatment, in a seamless manner to maintain cosmesis.

Specialising in breast-conserving cancer surgery and reconstruction for breast cancer patients, in addition to consulting patients for breast reduction, breast enlargement (augmentation) and breast lift procedures, has allowed Dr. Ong to apply his extensive experience to clients of the wider community.

Dr. Ong also provides a specialist, multidisciplinary treatment approach to breast, thyroid, and melanoma cancer patients, involving a professional team of medical oncologists, radiation oncologists, radiologists, pathologists, physiotherapists, McGrath Foundation Breast Care nurses and allied professionals.

General and laparoscopic surgery services, with a particular interest in the gallbladder, thyroid and parathyroid surgery and hernia repairs, in addition to endoscopy (gastroscopy and colonoscopy) services are also available to clients.

Teaching medical students and surgical registrars is a passion for Dr. Ong, who was recently awarded the “Excellence in Surgical Teaching Award for Best Surgical Teacher in Western Australia, 2016”.

Dr. Ong continues to provide expert care to his south-west patients with compassionate and professional care.
