Which conditions is (PDT) used to treat?

Photodynamic therapy (PDT) is an effective treatment for actinic (or solar) keratoses and Bowen’s disease, which are pre-cancerous conditions that can develop into invasive squamous cell carcinoma (SCC), a potentially serious form of skin cancer, if left untreated. Photodynamic therapy is an extremely useful treatment for superficial basal cell carcinoma (BCC), which is a very slow growing form of the commonest skin cancer. There is increasing evidence that photodynamic therapy can in expert hands photodynamic therapy can be used instead of surgery for carefully selected forms of nodular (raised) basal cell carcinoma. Photodynamic therapy is never used to treat invasive squamous cell carcinoma (SCC), or melanoma, which usually require complete surgical removal.
