Photodynamic therapy (PDT) is an emerging treatment used to eradicate premalignant and early-stage cancer and reduce the tumour size in end-stage cancers. Its mechanism of action involves three key components: a photosensitizer, light (wavelength appropriate for the photosensitzer), and tissue oxygen. The combination of these three components leads to the destruction of tumor cells.
