Profile

Asst Prof Sabrina Ngaserin is Head of Breast Surgery, Sengkang General Hospital, Chief of Service, SingHealth Duke-NUS Breast Centre and a Consultant in the Department of Surgery, Sengkang General Hospital.

Asst Prof Ngaserin graduated with a Bachelor of Medicine and Surgery from the Faculty of Medicine, National University of Singapore (NUS) in 2010. She completed her general surgery residency and received her initial breast specialist training at the National University Hospital of Singapore (NUH). In this period, she completed her membership examination of the Royal College of Surgeons of Edinburgh (Surgery) and obtained Master of Medicine (Surgery) from the National University of Singapore. She is an accredited Fellow of the Royal College of Surgeons of Edinburgh (General Surgery) and a Fellow of the Academy of Medicine of Singapore. She is fellowship trained in Advanced Oncoplastic Breast Surgery with the Fiona Stanley and Fremantle Hospital Group (FSFHG), Australia. She has also done surgical observerships in Korea, and completed endo-robotic surgical training masterclasses and workshops in Taiwan. She currently practices at Sengkang Hospital’s Department of Surgery, sub-specialising in breast surgical oncology, breast surgery, and is one of the few surgeons in Singapore formally trained in oncoplastic breast surgery, minimally invasive and endoscopic breast surgery.

Besides pursuing clinical excellence, Asst Prof Sabrina is passionate about under- and post-graduate education and academic teaching. She holds several academic positions including Assistant Professor of Duke-NUS Post-graduate Medical School, Clinical Block Lead of Surgery for Lee Kong Chian School of Medicine, is Clinical Faculty with the Yong Loo Lin School of Medicine, National University of Singapore, Physician Faculty with SingHealth’s Post-Graduate Year 1 (PGY1) Program and Physician Faculty with SingHealth’s General Surgery Residency Program. She is also Programme Director (PD) of the SKH Advanced Breast Surgery Fellowship programme. She is actively involved in a wide range of breast and general surgery research, has published over 20 scientific articles in peer-reviewed journals, and presents her surgical and scientific work regularly in local, regional and international conferences and meetings. With an interest in hospital administration, service and systems development, she takes pride in her multidisciplinary, collaborative, co-creation - the SKH Breast Centre’s 1-Stop BrEAST (One Stop Breast Evaluation, Accelerated Screening and Treatment) service, and is an active member of the SKH Medical Board.

Her breast and surgical oncology practice covers breast cancer screening and detection, benign breast diseases, breast cancer evaluation, diagnosis, counselling, surgical management, and surveillance. Experienced in a wide range of breast procedures, she performs minimally invasive image-guided breast biopsies, breast lump and lesion excisions, localisation procedures under ultrasound, wire, magnetic seed, and radar guidance, oncological breast cancer surgeries such as breast conserving cancer surgery, including that with oncoplastic breast surgery such as mastopexy, mammoplasty, and intercostal artery perforator flaps, intraoperative radiotherapy, mastectomies including simple mastectomy, skin-sparing and nipple-sparing mastectomy and minimally-invasive endoscopic surgery with immediate (or delayed) breast reconstruction, sentinel lymph node biopsy, targeted axillary dissection, and axillary lymph node dissection/clearance. She works closely with a multidisciplinary team including breast radiologists, pathologists, medical oncologists, radiation oncologists, gynaecologists, genetic counsellors, specialist breast nurses, psychologists, occupational therapists, and plastic and reconstructive microsurgeons. She also manages patients for general surgical conditions, performs screening, diagnostic and therapeutic endoscopy, and operative procedures, including laparoscopic surgery for other general surgical conditions.

Asst Prof Sabrina’s main interest is in cutting edge breast cancer surgical techniques that considers the patients oncological safety alongside their need for aesthetic quality of life preserving surgical solutions. She is particularly passionate about minimally invasive breast surgery, tailoring ‘off-the-breast’ ‘minimal-access’ incisions to provide the illusion of ‘nearly-scarless’ breast resections. She believes in meticulous diagnostic and therapeutic discussions, followed by the creation and tailoring of a personalised oncoplastic approach involving multidisciplinary services, to guide each patient and their loved ones through their treatment journey and survivorship.
