Our Experience With Photodynamic Diagnosis and Photodynamic Therapy for Lung Cancer [PDF]

Journal of the National Comprehensive Cancer Network, 2012
The diagnosis of lung cancer was significantly enhanced by the development of the fiberoptic bronchoscope in 1965. Since then, advances in photosensitizers and light sources have brought photodynamic medicine into the light. This article offers an historic overview of the emergence of photodynamic medicine through the perspective of a pioneer with more
