Daylight Activated Field Therapy
Photodynamic therapy is a form of skin cancer treatment that uses photosensitizing agents & lights to help kill cancerous and precancerous cells. To do so, a topical prescription cream, like Metvix is applied to the skin, by a physician. These medications are highly selective and only responds to precancer and cancer cells. After your physician has applied the medication to your “sunscreened” skin, you will expose the area of skin to daylight for 150 minutes. The outside temperature needs to be a minimum of 12 degrees celsius for this drug to be effective. There is no pain associated with the activation of the medication. After 150 minutes the medication will be washed off, and that concludes one cycle of treatment. Patients typically need 1-3 treatment cycles.
