Mr Harun Thomas
Professional statement
Mr Harun Thomas is a leading consultant oncoplastic breast surgeon based in Southend-on-Sea and Chelmsford who specialises exclusively in breast surgery and the management of breast cancer, breast lumps, breast pain, and other breast symptoms. With over 25 years’ experience, he currently consults privately at Spire Wellesley Hospital and Springfield Hospital, where he holds one-stop breast clinics.
As a specialist, Mr Thomas is able to provide the full range of breast surgical procedures, including mastectomy, breast-conserving surgery, wide local excision (lumpectomy) alongside (implant-based) breast reconstruction, sentinel lymph node biopsy and axillary surgery. He also offers breast screening and assessments for male breast diseases such as gynaecomastia. His special interests are therapeutic mammaplasty (the use of plastic surgical techniques in breast surgery to improve clinical and aesthetic outcomes) and intra-operative ultrasound (using ultrasound during surgery to improve surgical outcomes).
Mr Thomas, who sees over 1,500 patients with breast symptoms every year, is one of the few surgeons in the UK to have completed both a Masters in Oncoplastic Breast Surgery – Europe’s highest qualification in the specialism area – and the prestigious National TIG Oncoplastic fellowship. He also has a Masters in General Surgery and a Diplomate from the National Board of Examination, and is a fellow of the Royal College of Surgeons of England since 2013. Within the NHS, Mr Thomas is a consultant oncoplastic breast surgeon at Southend University Hospital, where in addition to his regular consultant duties, he is also an education lead.
Beyond his high-quality breast surgical practice, Mr Thomas has previously served as president of the UK Breast Surgery Trainees Association and as an ex officio committee member of the Association of Breast Surgery, UK. He is, at present, an honorary senior lecturer and module lead at the University of East Anglia, and the author of several publications in peer-reviewed academic journals.
