Photodynamic Therapy (PDT)
Using special light against cancer – a new treatment modality.
In Photodynamic Therapy (PDT) light is used to destroy cancer tissue.
How is it used?
A special dye is positioned in or on tissue where it specifically accumulates in the tumor tissue. By using a special light, usually a laser, the area is made fluorescent. Damage to the tumor cell and subsequent cell death is produced. This curative approach is aimed at superficial cutaneous and mucosal tumors because of the depth of the light penetration. PDT is more and more used in palliative oncology since it allows for interstitial application of thin light applicators which effectively destroy the tumor in a minimally invasive manner, with the least discomfort for the patient.
