PDT
Photodynamic Therapy
Photodynamic therapy (PDT) is a treatment that uses special drugs, sometimes called photosensitizing agents, along with light to kill cancer cells. The drugs only work after they have been activated or “turned on” by certain kinds of light.
Aminolevulinic acid (ALA or Levulan) is a drug that's applied to the skin. It’s used to treat actinic keratosis (AK), a skin condition that can become cancer, and is used only on the face or scalp. A special blue light, rather than laser light, is used to activate this drug.
PDT is an in-office procedure. This means that you can get the procedure done without having to be admitted into a hospital or stay in the doctor’s office after treatment for too long. This also means that you’ll stay awake during the procedure.
