Please see basal cell carcinoma.
Basal Cell Carcinoma, This condition also known as a "rodent ulcer" is the commonest skin cancer. It is usually not very serious, but does need an expert to treat it.
The great majority of these lesions do not spread anywhere else and can be treated on the skin surface relatively easily. They are related to sunshine exposure and therefore typically occur on the face and other areas of the body exposed to sunshine.
They usually progress and enlarge only very slowly. Treatment is by surgical removal if possible. Other types of treatment include Cyrotherapy or treating the skin with X-rays. There are now a variety of additional ways of treating Basal Cell Carcinoma including specialised creams, specialised light and laser treatments for example Photo Dynamic Therapy (PDT) and specialised types of surgery for example MOH's Surgery.
If you are worried about a possible Basal Cell Carcinoma or have been referred to the hospital and are waiting too long, consider using 'consult the specialist' for my expert opinion.
