Clin Assoc Prof Lim Geok Hoon

A/Prof Lim Geok Hoon is trained in oncoplastic breast surgery and believes that achieving a good cosmetic breast result is as paramount as ensuring a safe oncological outcome. She has several publications, with most of her work focusing specifically on surgical oncoplastic techniques most applicable to Asian women. She also has a special interest in genetic breast cancer, which is why she pursued a year-long fellowship in the United Kingdom on breast cancer genetics and oncoplastic surgery. She founded the Singapore Breast Oncoplastic Surgery Symposium (SBOSS) in 2015 and developed the world's first virtual simulator for teaching oncoplastic surgery. She also pioneered the minimal scar mastectomy technique.
