  ACTINIC KERATOSIS (EARLY SKIN CANCER): PDT with Levulan
 
 
What is it?
"Actinic" means "as a result of the sun" and "Keratosis" means "hardening of the skin". This type of cancer manifests itself many years after the skin has been damaged by the sun. An actinic keratosis is a scaly or crusty bump that forms on the skin surface. They are also called solar keratosis or pre-cancerous spots. Dermatologists call them "AK's" for short. They range in size from as small as a pinhead to over 2cm. They may be light or dark, tan, pink, red, a combination of these, or the same color as ones skin. The scale or crust is horn-like, dry, and rough, and is often recognized easier by touch rather than sight. Occasionally they itch or produce a pricking or tender sensation, especially after being in the sun. They may disappear only to reappear later. Keratosis are most likely to appear on sun exposed areas: face, ears, bald scalp, neck, backs of hands and forearms, and lips. They may be flat or raised on appearance.
 
How does PDT with Levulan work?
PDT with Levulan is a non-surgical technique using Levulan, a topical photosensitizer of 20% Aminolevulinic Acid. During this advanced technique, Levulan is first applied to the area. After 30- 60 minutes, the area is then exposed to the Photo Dynamic Intense Pulsed Light (IPL). It can be applied directly on particular lesions or to an entire area. Levulan will increase sun sensitivity for 48 hours after it is applied so it is important that patients protect treated areas from the sun during this time period.
 
Is there anything my doctor should know before I begin treatment?


Your doctor should be told:

• If you have porphyria or known allergies to porphyrins
• If you are allergic to any of the system’s components
• The names of any medications you are presently taking
• If you are pregnant or nursing
• Photosensitivity
• If you have inherited or acquired blood-clotting defects
