Mr Duraisamy Ravichandran MBBS, FRCS PhD

My main clinical interest is in breast cancer, thyroid disorders and hernia’s. My higher surgical training was in Wessex and East Anglia and I trained in breast and endocrine surgery at Norfolk & Norwich and Addenbrookes Teaching Hospitals. My PhD was in surgical oncology (Southampton University Surgical Unit). I was appointed as a Consultant Surgeon in 2001. Most of my elective work is with breast cancer, thyroid lumps including thyroid cancer, parathyroid disorders and hernias, and I also do emergency on-call for my NHS hospital for all general surgical emergencies.

I am an active clinical researcher in breast cancer with a large number of published papers in peer-reviewed journals and national and international presentations. I also train surgeons, teach medical students from UCL and am an examiner for the Royal College of Surgeons as well as Final MBBS examiner. I am presently the lead clinician for breast cancer for the Mount Vernon Cancer Network.

I see patients with breast complaints, thyroid lumps, hernias and other lumps in my clinic. I offer open repair for umbilical, inguinal, femoral and incisional hernias. I also see patients with lymphadenopathy and other “lumps and bumps”.
