Photodynamic Therapy (PDT)

Photodynamic therapy (PDT) is a modern treatment for certain types of non-melanoma skin cancer (NMSC) as well as precancerous skin lesions.

The treatment consists of applying a special light sensitising cream to the skin lesion and 3 hours later, shining a pure red light on it. The pure light is a weak harmless light. Only where the two are combined will they treat the abnormal area of your skin.

PDT offers a non surgical alternative treatment for skin lesions. The number of PDT treatments will be dependent on the type of lesion that is being treated. Actinic keratoses usually require a single treatment of PDT but basal cell carcinomas and Bowens disease require two treatments one week apart.
