Mr Alexander (Sandy) Leeper

Mr Alexander Leeper is a Consultant Oncoplastic and Reconstructive Breast Surgeon offering modern, individualised care for all aspects of breast disease — from symptom assessment to cancer surgery and reconstruction. He specialises in using advanced plastic surgical techniques to preserve or restore breast aesthetics without compromising oncological safety.

Mr Leeper completed his surgical training in Edinburgh, gaining his MD in translational breast cancer research, and subsequently undertook higher surgical training in East Anglia and London. He was awarded Distinction by the University of East Anglia’s prestigious Mastership in Oncoplastic Breast Surgery. He went on to complete the prestigious national Oncoplastic Breast (TIG) fellowship, regarded as the gold standard for Breast reconstructive training in the UK at St Bartholomew’s Hospital in London.

He currently works across King Edward VII’s Hospital in London, James Paget University Hospital and the Norfolk & Norwich Hospital.

He treats the full spectrum of benign and malignant breast conditions, including patients with a family history of breast cancer and those seeking risk-reducing surgery. His surgical repertoire includes therapeutic mammoplasty, mastopexy, sentinel node biopsy, wide local excision, and advanced partial breast reconstruction using chest wall perforator flaps (such as LiCAP and LTAP), as well as full implant-based reconstruction and lipofilling techniques.

Mr Leeper is passionate about delivering contemporary, patient-centred care and is committed to clear communication and shared decision-making. His holistic approach ensures that each patient receives a management plan that is not only oncologically sound but also preserves body confidence and quality of life.

He has particular expertise in:

• Screen-detected breast cancer
• Management of breast lumps, pain, nipple discharge, and other breast symptoms • Genetic/familial breast cancer risk and risk-reducing surgery
• Oncoplastic and reconstructive breast surgery
• Fat grafting and chest wall perforator flap reconstruction

Mr Leeper leads the BEAM research programme, a Breast Cancer Now–funded study exploring the link between gut microbiota and breast cancer risk. He is active in global surgical education and has worked in low-resource settings including Egypt, Nepal, Rwanda, and the Solomon Islands.

He offers One-Stop Diagnostic Clinics and welcomes insured and self-pay patients with or without GP referral.
