What are the advantages of Photodynamic Therapy (PDT)?

The major advantage of photodynamic therapy is that it is completely non-invasive (no injections or surgery) and is quick, so that a skin cancer or pre-cancer can be successfully treated in just one or two treatment sessions (a week apart). The alternative to photodynamic therapy is usually surgery, which leaves a scar or application of anticancer creams, which although effective can cause quite significant inflammation (redness and crusting) for several weeks. Photodynamic therapy usually leaves no visible scar. Depending on the type of skin lesion your dermatologist may suggest that surgery, cryotherapy or other treatments are more appropriate than photodynamic therapy.
