Are there any medical applications of sun sensitivity (photosensitivity)?

Photodynamic therapy utilizes the concept of sun or light sensitivity to treat some skin conditions including skin pre-cancers (actinic keratosis), skin cancers, and acne. Briefly, this treatment takes advantage of activating a photosensitizing drug (such as 5-aminolevulinic acid) by shining light directly onto it for a short time. The drug is first applied to the area of the skin where the cancer or pre-cancer is found. With light-induced activation of the drug, the abnormal cells (cancer or pre-cancer) are destroyed preferentially.
