Photodynamic Therapy, or PDT is a sometimes called Blue Light treatment for skin cancer. It treats  pre-cancer cells pre-clinically beneath the surface. Sarah, our Physician Assistant answers questions about PDT while the patient is undergoing the Blue Light  treatment for 16 minutes and 40 seconds.

Some of the patients get the benefit of having smoother skin, a cosmetic overlap from the treatment, even though they are being treated for pre-cancer.
