Miss Harleen K Deol

Consultant Oncoplastic Surgeon

MBBS, MSc, DipIC, FRCS (General Surgery)

Specialises in

I am a Breast Surgeon specialising in the diagnosis and management of breast cancer. My approach is to provide clear and concise information/explanations to my patients, up-to-date and evidence-based treatment focusing on the medical management of breast cancer, psychological support for patients through their treatment and a range of innovative surgical methods appropriately.

As a Consultant Breast Surgeon, I incorporate the latest plastic surgery techniques in the management of breast cancer, (Oncoplastic Breast Surgery) allowing for an improved cosmetic outcome and breast appearance after surgery. These have the proven benefit of better psychological recovery from the impact of breast surgery.

I treat breast problems of any nature, benign or cancerous and patients with a family history of breast cancer. I perform immediate and delayed breast reconstructions and symmetrisation surgery (breast reduction or augmentation) in patients with breast cancer.

Further specialist interests: patients with a family history of breast cancer and risk-reducing surgery; screen-detected breast cancer; management of the range of benign breast conditions and lumps affecting women of all ages; male breast cancer and lumps; breast problems in young women and children.

Having qualified as a doctor from Barts and the Royal London in 1997, I was the first woman to enter the Royal London Hospital General Surgical Rotation in over 20 years. Further senior specialist General Surgical training was in the highly regarded, North-East Thames rotation in London, where I also undertook a Paediatric Surgery fellowship at the Royal London Children’s Hospital.

Specialising in Breast Surgery, I gained extensive training in numerous London Breast Units and the Royal Marsden Hospital (Sutton), prior to being awarded a prestigious British Association of Surgical Oncology Oncoplastic Breast Surgery National Fellowship.

In addition, I have presented her research work at National and International medical conferences, as well as being a contributing author of a chapter in a Surgical Oncology textbook. I am an active trainer for junior surgeons and medical students, specialising in the teaching of clear communication to patients, women’s health, Breast surgery and General Surgery.
