"Breast surgery is a highly personalised field, where patients have the autonomy to decide on their choice of surgical treatment. My role, as a breast surgeon, is to walk with my patient in the journey of battling breast cancer and guide them through to the closure of their breast conditions. It is most rewarding to me when I see my patients return to normal life especially after breast cancer treatment. I strive to provide my patients with compassionate, evidence based, and equitable care."
