About Dr. Alexander Leeper

Mr Alexander (Sandy) Leeper is a Consultant Oncoplastic and Reconstructive Breast Surgeon working at James Paget University Hospital in Norfolk, alongside a busy private practice at OneWelbeck and King Edward VII’s Hospital in London. He specialises in the full spectrum of breast disease, offering rapid diagnosis, personalised treatment pathways and the latest oncoplastic surgical techniques. His expertise spans breast-conserving surgery, complex breast reconstruction, genetic risk assessment and the management of both benign and malignant breast conditions.

Mr Leeper is committed to achieving the safest cancer outcomes while preserving or enhancing cosmetic results. He is highly skilled in advanced oncoplastic approaches, including therapeutic mammoplasty, chest wall perforator flaps and modern implant-based reconstruction methods. He has a particular interest in supporting patients with a strong family history of breast cancer, offering comprehensive risk assessment and tailored risk-reduction strategies.

Appointed as a Consultant Oncoplastic Surgeon in 2021, Mr Leeper completed the prestigious TIG fellowship in London and holds an MD from the University of Edinburgh, where he focused on innovative 3D breast cancer modelling. Alongside his clinical commitments, he plays a leading role in research and innovation. He is the principal clinical investigator for the BEAM study, an ambitious project exploring the relationship between the gut microbiome and breast cancer development, funded by a £250,000 Breast Cancer Now grant.

Mr Leeper is also actively involved in healthcare education, digital transformation and global health initiatives, contributing to the implementation of electronic health records and supporting surgical training programmes in low- and middle-income countries..

Mr Leeper put me at ease immediately. He took the time to understand my journey so far, which made me feel genuinely seen and heard. He is a positive communicator—articulate, clear, and extremely empathetic. He provided results promptly and always ensured I understood the next steps. His professionalism, compassion, and excellent communication made the entire experience reassuring and straightforward.

As a patient you are given the results of the exam with clear diagnosis and information about the findings of your condition . Although it is in a positive manner you are prepared in case the condition progresses or at that time the full picture is not available . I think the first appointment is a shock , and hasn’t sunk in that everything wasn’t ok in the mammogram , so I think a little more basic information is good . Although it was explained well it doesn’t go in . A little repetition would be good . That of course is down to each individual’s response. All the staff and especially Dr Leeper come across and concerned , supportive and approachable . A really lovely team that makes you feel cared for . This I haven’t experienced before and was so grateful for . In a difficult situation I was put at ease. With Dr Leeper I felt in good hands that he saw my individual condition and lodgically and kindly put me at ease . An approachable doctor . I thank him for his care and sharing information in such a clear and kind way . Anyone that comes before Dr Leeper with have the confidence that you are getting the best treatment for your condition and behind him the best team . I feel grateful for such care.

A very positive experience. Dr Leper has looked after my mum with the utmost care and compassion. All along this journey, he has guided my mum, clearly outlining her treatment and both my mother and I would highly recommend him as a phenomenal Consultant/ Surgeon.

Dr Leeper treated me with the utmost respect, care, kindness and professionalism. I found Dr Leeper to be incredibly charming, approachable and kind. I felt so relaxed and comfortable in Dr Leeper’s presence. Dr Leeper took the time to interpret my breast scan results to me in clear simple language which I would otherwise not have understood well. Mr Leeper is a lovely man and a very professional, knowledgeable, and caring Doctor. I highly recommend Dr Leeper for his expertise and excellent care. Thank you.
