Photodynamic Therapy (PDT) in Portland, Oregon treats actinic keratoses (precancerous lesions), certain types of skin cancer, and acne.
PDT is a two-stage treatment combining light energy with a drug (photosensitizer) to destroy said cancerous and precancerous cells after light activation while leaving normal cells intact. The treatment consists of application of a sensitizing agent – either Levulan (aminolevulinic acid 20%) or Metvixia (methyl aminolevulinate 16.8%) – which is left on the skin and allowed to be absorbed by the abnormal tissue for approximately 1 to 2 hours, followed by exposure to intense light for 15 minutes.
The chemical photosensitizer is activated by specific wavelengths of light energy. When it is triggered, it becomes toxic to the targeted tissue, making them very sensitive to light, which destroys the malignant cells. So it is very precise and controlled, minimizing any effect on the surrounding tissues.
After a short healing period, new skin cells replace the abnormal cells. Studies show that this light-based therapy promotes the body’s immune response, helping it destroy cancerous and precancerous cells.
