Mr Kaiyumars Contractor

  • FRCSEd, Phd, FEBS
  • Consultant Oncoplastic Breast Surgeon


I did my primary under-graduation degree from Bombay, India and then pursued my Post-graduation for the MS (Master of Surgery) degree at Tata Memorial Cancer Centre India where I trained in all aspects of Oncosurgery. I currently am appointed as substantive Consultant Breast Surgeon at Frimley NHS Foundation Trust.

I came to the UK in 2000 and have trained in all aspects of my sub-specialist interest of Breast Surgery at well-known tertiary NHS Trusts including Oncoplastic fellowships at Charing Cross Hospital- Imperial College, Guy’s and St Thomas NHS and St George’s NHS Trust.

My research interests are around imaging response to cancer therapies and I have undertaken formal research towards this and was awarded a PhD from Imperial College London in 2011.

I have published extensively as well as have numerous regional, national and international publications in various aspects of breast cancer and also from my formal research work.

I follow a multidisciplinary approach to treat breast conditions including cancer to ensure the best clinical outcome for my patients. I have more than 20 years of experience in performing breast surgery including being up to date with all the latest techniques including nipple-saving mastectomy with immediate breast reconstruction using the pre-pectoral approach
