Photodynamic therapy may be one of the cures for lung cancer

Photodynamic therapy may be one of the cures for persons with inoperable lung cancer. Photodynamic therapy begins with the injection of a light-activated drug (e.g., photofrin/polyhaematoporphyrin, lumin). Then, during bronchoscopy (examination of the airways using a flexible scope), the lung tumor is illuminated by a laser fiber that transmits light of a specific wavelength. At that time, the laser light is used to destroy the sensitized tumor tissue. Skin photosensitivity (light sensitivity) is a side effect of PDT. The curative potential of PDT is the most exciting aspect of this therapy in lung cancer patients whose tumors are hidden on chest X-ray. The tissue-sparing effects of PDT may be particularly important for individuals with limited lung function.
