Photodynamic therapy (PDT) is a modern, highly effective treatment for certain types of pre-cancerous lesions as well as non-melanoma skin cancers.
PDT only treats the abnormal skin cells resulting in minimal or no scarring
PDT uses a laser combined with a light sensitive drug to destroy cancer cells. The treatment is normally given in two stages:
The first stage of the treatment involves applying a cream to the skin lesions, there is then a short delay between the cream being applied and the next stage of the treatment. This allows time for the drug to concentrate on the cancer cells.
The second stage of the treatment involves a strong red light shining directly on the affected area for a few minutes. The light and cream targets the skin lesion cells only leaving the healthy skin unharmed.
PDT only treats the abnormal skin cells resulting in minimal or no scarring. This procedure does not require an anaesthetic and it is performed in our out-patients department.
