Dr Ong contributes to the care of breast cancer patients in Macarthur through the following initiatives:

  • Acquisition of a wireless sentinel node probe – the Neoprobe. Narrower targeting means potentially smaller incisions and less dissection of tissues.
  • Dr Ong partners with plastic surgeons to offer a range of breast reconstruction after cancer surgery.
  • First surgeon to setup on-site hookwire services at the public hospital. Breast cancer patients do not have to travel between different sites which can reduce stress and anxiety on the day of surgery.
  • First surgeon to introduce current generation real-time tissue perfusion monitoring (Stryker’s SPY) to oncoplastic breast surgery.
  • Introduction of oncoplastic surgical techniques for treatment of breast cancer and leading the introduction of oncoplastic breast surgery at Campbelltown and South West Sydney.
  • Lead clinician for breast surgery Model of Care in Macarthur/SWSLHD.

High-resolution ultrasound scans are conducted by Dr Ong in his private consulting rooms to assist with diagnosis and management of breast diseases.

Dr Ong is passionate about the holistic care and quality management of patients with breast cancer. Newly diagnosed breast cancer patients can often be seen in the same day or within 1-2 days of their diagnosis.
