Photodynamic Therapy
Photodynamic Therapy (PDT) is a non-invasive treatment that uses a light-sensitive cream and red light to destroy abnormal skin cells.
How does PDT work?
A photoactivated cream called Metvyx (5-ALA) is applied to the treated area. The skin cancer cells absorb Metvyx cream and produce photoactive porphyrins. The porphyrins are then exposed to red light which then produce reactive oxygen species which destroys the skin cancer.
How many treatments will I need?
One treatment for actinic keratoses (pre-cancerous sun spots).
Two treatments (2 to 3 weeks apart) for squamous cell carcinoma in situ (Bowen’s disease) and superficial basal carcinomas.
