What is the primary mechanism of Photodynamic Therapy?
What is the primary mechanism of Photodynamic Therapy?
- Using light energy alone to damage abnormal tissues
- Directly inducing apoptosis in tumor cells
- Stimulating the host immune response through chemical reactions
- Combining light energy with a photosensitizer to activate its toxic effects (correct)
What is the effect of light activation on the photosensitizer?
What is the effect of light activation on the photosensitizer?
- It has no effect on the photosensitizer's properties
- It increases the photosensitizer's toxicity to normal tissues
- It makes the photosensitizer inert
- It makes the photosensitizer toxic to the targeted tissue (correct)
