Background Information 
Professional profile:

Dr McKenna is a Consultant Dermatologist experienced in the diagnosis and care of all aspects of skin problems. He has particular expertise in the early diagnosis and the surgical management of skin cancers and believes in taking the time to listen to his patients, fully explaining the diagnosis and all appropriate treatment options.

Dr McKenna graduated from Glasgow University. He completed his specialist dermatology training in Belfast where he was involved in research to improve computed assisted diagnosis of melanoma. He then went on to train in additional advanced dermatological surgery, lasers, and Mohs micrographic surgery for complex skin cancers in St Thomas' Hospital, London. Dr Mckenna is one of only a few consultants in the UK that have completed a prestigious Mohs Micrographic Surgery training fellowship in addition to their general dermatology training.

Dr McKenna moved to Leicester in July 2008 after being appointed as a Consultant Dermatologist with a specialist interest in dermatological surgery and skin cancer at Leicester Royal Infirmary. He quickly set up a much needed Mohs Micrographic Surgery service permitting access to this specialised treatment to patients across the region.

Dr Mckenna is the only Mohs micrographic surgeon in Leicester, accepting referrals from GPs and from other consultant colleagues both locally and regionally.

Dr Mckenna is the Deputy Lead for the Comprehensive Local Research Network for Leicester, Northampton, and Rutland. He promotes research and recruits to several national research studies, particularly in Psoriasis and Acne. He is also a collaborator in on-going research into Keloid scarring and experimental medical imaging of Basal Cell Carcinoma.

Personal profile:

Dr McKenna is married and has four young daughters. His free time is mainly spent trying to keep his children entertained.

He spends his holidays back in Ireland visiting relatives, fishing and boating when the weather allows.

Dr John Mckenna on skin cancer
“Skin cancer is by far the most common cancer in humans. Most people have heard of Melanoma, the potentially serious type that is usually a dark lesion on the skin, like a changing or new mole.

Thankfully however most skin cancers are the non-life threatening Basal Cell Carcinoma. This type of skin cancer does not spread around the body, but does grow slowly and steadily within the skin. They start as a small spot that may occasionally bleed and crust, and slowly enlarge over many months. They become really quite unsightly and troublesome, and when occurring on the face they can damage cosmetically important structures such as the eyelids and nostrils, eventually invading fat, muscle and cartilage.

There are a number of potential treatment options depending on the type of basal cell carcinoma, and its location, but surgical removal is often required. If they are occurring in places where there is adequate loose skin, then we remove them with a generous margin of surrounding normal looking skin, in order to have a good chance of complete cure.

When they occur near cosmetically important structures, have locally aggressive growth patterns, or when standard surgery has already failed, then Mohs Micrographic Surgery is considered the best possible treatment. This allows an exceptionally high level of confidence of complete cure without the need to remove large amounts of unnecessary surrounding normal skin. The wound size can be kept to the absolute minimum, reducing the damage and scarring from surgery.”
