Dr Mok Chi Wei graduated with a Bachelor of Medicine and Bachelor of Surgery (MBBS) on a Dean’s list in 2010 and subsequently joined Singhealth General Surgery Residency Programme from 2012 to 2017 for his postgraduate training. He was accredited as a specialist in general surgery in September 2017, with the fellowship examinations of the Royal College of Surgeons of Edinburgh (General Surgery), before sub-specialising in breast surgery in particular breast cancer surgery.

He is currently a consultant in the Department of Surgery, Changi General Hospital (CGH) with a subspecialty interest in breast surgery. His clinical practice is mainly on breast diseases, both benign and malignant. He completed his advanced fellowship in oncoplastic and minimally invasive (endoscopic and robotic) breast surgery. Dr. Mok also believes that the appearance of the breast after cancer resection is extremely important, and has developed two new minimally invasive breast surgery techniques, namely 3D Endoscopic Subcutaneous Mastectomy for treatment of gynaecomastia as well as Endoscopic-assisted ICG (EASI) technique for sentinel lymph node biopsy in breast cancer since returning from his fellowship.

Apart from his clinical commitments, he also teaches undergraduate and postgraduate students from the Yong Loo Lin School of Medicine, Duke-NUS Medical School and Lee Kong Chian School of Medicine, and he is currently appointed as a Clinical Assistant Professor with Duke-NUS Medical School.

In terms of research, Dr Mok has published extensively in breast cancer related topics and he also serves as a peer reviewer in Journal of Plastic & Reconstructive Surgery (JPRAS) and other breast and reconstructive surgery subspecialty journals. He has co-authored the first textbook on minimally invasive (endoscopic and robotic) breast surgery techniques which was published by Elsevier in January 2020.
