Sanjay is a dedicated, compassionate and highly respected Consultant Breast Surgeon. He is a current Council member for Breast Surgeons of Australia New Zealand (BreastSurgANZ), and he is also the immediate past President (May 2019 – May 2020).

Expertise

Sanjay is dedicated to the professional development of current and future surgeons. He is an Associate Professor of the University of Sydney with the Royal Prince Alfred Academic Institute, a lead researcher with the Institute, and has goals of developing a culture of academia within the Breast Department. In 2013, Sanjay’s work on Hedgehog signalling, in collaboration with the Garvan Institute, won the Patron’s Prize at the Royal Prince Alfred Hospital for best scientific research.

He is also the current Chairman of Post-Fellowship Training for BreastSurgANZ, a role that involves training future breast surgeons in both Australia and New Zealand.

A significant milestone for Sanjay was being co-founder of the first Postgraduate Degree specific to breast surgery, the Master of Advanced Surgery (Breast Surgery) at the University of Sydney.

Sanjay is a committed researcher in breast cancer medicine and surgery and has presented at many national and international conferences. These include being asked to present at the San Antonio Breast Symposium, the American Society of Clinical Oncology (ASCO), and the Cancer Institute in Bangkok (Thailand), as well as other guest presentations in Berlin (Germany), Singapore, Queenstown (New Zealand), Auckland (New Zealand) and across Australia.

In 2023, Sanjay was invited to join the Smith & Nephew’s Global SCC (Surgical Site Complication) Prevention Council Advisory Board which convened in London, England.

Associate Professor Sanjay Warrier is the immediate Past President of BreastSurgANZ, co-Chair of Post Fellowship Training, long-standing member of both the BreastSurgANZ Membership and Oncoplastic Committees, and sits on advisory committees with the NSW Ministry of Health and the Cancer Institute. He also sits on the Sydney Breast Cancer Foundation committee and the Research Faculty at the Chris O’Brien Lifehouse.

Sanjay is passionate about utilising novel techniques and innovative technologies to offer his patients the best options available. He was the first surgeon in Australia to utilise SPY technology for breast reconstruction surgery, and was the first surgeon in the Southern Hemisphere to perform robotic breast surgery. He was also an early adopter of volume replacement techniques for breast conserving surgery, and the first to utilise 3D printing for breast assessment and surgery planning.

Sanjay has also published many papers and co-authored articles in peer reviewed journals and magazines.
